Lauren Oliver's soon-to-be-released YA novel "Vanishing Girls" is a quiet kind of thriller -- a thriller that anyone with siblings will immediately relate to. We won't give too much away before the book's March release date, but -- lucky for you -- Oliver has given MTV News the first few chapters for exclusive premiere.

"Having a sister is weirdly amplifying -- you have a built-in friend, a built-in sympathizer, someone to share with and learn from -- and eviscerating -- you have a built-in competitor, someone who seems better, older, wiser, or just more loved," Oliver told MTV News of "Vanishing Girls," which tells the tale of sisters Nick and Dara and what happens between the two after a traumatic accident.

"Ultimately, there is no totally separating my identity from my sister, from our conflict and our shared history and our shared joy," Oliver added. "Our stories are intertwined. In 'Vanishing Girls,' that’s what I was aiming to write about: a shared story, two girls whose identities and lives are so deeply intertwined it’s impossible to conceive of one without the other."

Nick

Somerville and Main Heights are only twelve miles apart, but they might as well be in different countries. Main Heights is all new: new construction, new storefronts, new clutter, newly divorced dads and their newly bought condos, a small cluster of sheetrock and plywood and fresh paint, like a stage set built too quickly to be realistic. Dad’s condo looks out over a parking lot and a line of skinny elm trees that divides the housing complex from the highway. The floors are carpeted and the air conditioner never makes a sound, just silently churns out frigid, recycled air, so it feels like living inside a refrigerator.

I like Main Heights, though. I like my all-white room, and the smell of new asphalt, and all the flimsy buildings clinging to the sky. Main Heights is a place where people go when they want to forget.

But two days after the skinny-dipping incident, I’m heading home to Somerville.

“It’ll be good for you to get a change of scenery,” Dad says, for the twelfth time, which is stupid because it’s the exact thing he said when I moved out to Main Heights. “And it’ll be good for your mother to have you home. She’ll be happy.”

At least he doesn’t lie and say that Dara will be happy, too. Too fast, we’re entering Somerville. Just like that, from one side of the underpass to the other, everything looks old. Enormous trees line the road, weeping willows fingering the earth, tall oaks casting the whole car in flickering shadow; through the curtain of swaying green, enormous houses ranging from turn-of-the-century to colonial to who-the-hell-knows-how-long-ago are visible. Somerville used to be the seat of a booming mill and cotton factory, the largest town in the whole state. Now half the town has been granted landmark status. We have a Founders’ Day and a Mill Festival and a Pilgrims’ Parade.

There’s something backward about living in a place so obsessed with the past; it’s like everyone’s given up on the idea of a future.

As soon as we turn onto West Haven Court, my chest goes tight. This, too, is the problem with Somerville: too many memories and associations. Everything that happens has happened a thousand times before. For a second, an impression surfaces of a thousand other car rides, a thousand other trips home in Dad’s big Suburban with the rust-colored coffee stain on the passenger seat -- a composite memory of family trips and special dinners and group errands.

Funny how things can stay the same forever and then change so quickly.

Dad’s Suburban is now for sale. He’s looking to trade it in for a smaller model, like he traded his big house and four-person family for a downsized condo and a perky, pint-size blonde named Cheryl. And we’ll never drive up to number 37 as a family again. Dara’s car is in the driveway, boxed in between the garage and Mom’s: the pair of fuzzy dice I bought her at a Walmart still hanging from the rearview, so dirty I can make out handprints near the gas tank. It makes me feel a little better that she hasn’t thrown them away. I wonder if she’s started driving again yet.

I wonder if she’ll be home, sitting in the kitchen alcove, wearing a too-big T-shirt and barely there shorts, picking her toenails like she always does when she wants to drive me crazy. Whether she’ll look up when I come in, blow the bangs out of her eyes, and say, “Hey, Ninpin,” as if nothing has happened, as if she hasn’t spent the past three months avoiding me completely. Only once we’re parked does Dad seem sorry for off-loading me.

“You gonna be okay?” he asks. “What do you think?” I say.

He stops me from getting out of the car. “This will be good for you,” he repeats. “For both of you. Even Dr. Lichme said...”

“Dr. Lichme’s a hack,” I say, and climb out of the car before he can argue. After the accident, Mom and Dad insisted I ramp up my sessions with Dr. Lichme to once a week, like they were worried I’d crashed the car deliberately or maybe that the concussion had permanently screwed up my brain. But they finally stopped insisting I go after I spent a full four sessions at $250 an hour sitting in complete and total silence. I have no idea whether Dara’s still going.

I rap once on the trunk before Dad pops it. He doesn’t even bother getting out of the car to give me a hug, not that I want one -- just rolls down his window and lifts his arm to wave, like I’m a passenger on a ship about to set sail.

“I love you,” he says. “I’ll call you tonight.”

“Sure. Me too.” I sling my duffel over one shoulder and start traipsing toward the front door. The grass is overgrown and clings wetly to my ankles. The front door needs painting and the whole house looks deflated, like something integral inside has collapsed.

A few years ago my mom became convinced that the kitchen was slanted. She would line up frozen peas and show Dara and me how they rolled from one end of the counter to the other. Dad thought she was crazy. They got in a big fight about it, especially since he kept stepping on peas whenever he went barefoot to the kitchen for water at night.

It turned out Mom was right. Finally she had someone take a look at the foundation. Because of the way the ground had settled, it turned out our house leaned a half inch to the left -- not enough to see, but enough to feel.

But today the house looks more lopsided than ever.

Mom hasn’t yet bothered to switch out the storm door for the screen. I have to lean on the handle before it will open. The hallway is dark and smells faintly sour. Several FedEx boxes are stacked underneath the hall table, and there’s a pair of rubber gardening boots I don’t recognize, soles caked with mud, abandoned in the middle of the floor. Perkins, our sixteen-year-old tabby, lets out a plaintive meow and trots down the hall, twining himself around my ankles. At least someone is happy to see me.

“Hello?” I call out, embarrassed that I suddenly feel so awkward and disoriented, as if I’m a stranger.

“In here, Nick! ” Mom’s voice sounds faint through the walls, as if it’s trapped there.

I dump my bags in the hall, careful to avoid the mud splatter, and make my way toward the kitchen, the whole time imagining Dara: Dara on the phone, Dara with knees up in the windowsill, Dara with new streaks of color in her hair. Dara’s eyes, clear as pool water, and the small upturned knob of her nose, the kind of nose people pay for. Dara waiting for me, ready to forgive.

But in the kitchen, I find Mom alone. So. Either Dara’s not home, or she has decided not to grace me with her presence.

“Nick.” Mom seems startled when she sees me, though of course she heard me come in and has been expecting me all morning. “You’re too thin,” she says when she hugs me. Then: “I’m very disappointed in you.”

“Yeah.” I take a seat at the table, which is piled high with old newspapers. There are two mugs, both half-filled with coffee now showing a milk-white sheen, and a plate with a piece of half-eaten toast on it. “Dad said.”

“Really, Nick. Skinny-dipping?” She’s trying to pull the disapproving-parent act, but she isn’t as convincing as Dad was, as if she’s an actress and already the lines are boring her. “We’re all dealing with enough as it is. I don’t want to have to worry about you, too.”

There she is, shimmering between us like a mirage: Dara in short-shorts and high heels, lashes thick with mascara, leaving dust on her cheeks; Dara laughing, always laughing, telling us not to worry, she’ll be safe, she never drinks, even as her breath smells like vanilla vodka; Dara the beautiful one, the popular one, the problem child everyone loves -- my baby sister.

“So don’t,” I say bluntly.

Mom sighs and takes a seat across from me. She looks like she’s aged a hundred years since the accident. Her skin is chalky and dry, and the bags under her eyes are a bruise-y yellow color. The roots are showing at her scalp. For a second I have the worst, most vicious thought: No wonder Dad left.

But I know that isn’t fair. He left even before things got shitty. I’ve tried to understand it a million times, but still, I can’t. Afterward, sure. When Dara got metal pins in her kneecaps and swore she would never speak to me again, and when Mom went silent for weeks and started taking sleeping pills every night and waking up too groggy to go to work and the hospital bills kept coming, kept coming, like autumn leaves after a storm.

But why weren’t we good enough before?

“Sorry about the mess.” Mom gestures to encompass the table and the window seat, cluttered with mail, and the countertop, also heaped with mail and groceries half unpacked from a bag and then abandoned. “There’s always so much to do. Ever since I started work again...”

“That’s okay.” I hate hearing my mom apologize. After the accident, all she did was say I’m sorry. I woke up in the hospital and she was holding me, rocking me like a baby, repeating it over and over. Like she had anything to do with it. Hearing her apologize for something that wasn’t her fault made me feel even worse.

I was the one driving the car.

Mom clears her throat. “Have you thought about what you’ll do this summer, now that you’re home?”

“What do you mean?” I reach over and take a bite of the toast. Stale. I spit it out into a balled-up napkin, and Mom doesn’t even lecture me. “I still have shifts at the Palladium. I’ll just have to borrow Dara’s car and...”

“Absolutely not. No way you’re going back to the Palladium.” Mom turns, suddenly, into her old self: the principal-for-one-of-the-worst-public-high-schools in Shoreline County, the mom who broke up physical fights between the senior boys and made absentee parents get it together, or at least do a better job of pretending. “And you’re not driving, either.”

Anger itches its way up through my skin. “You’re not serious.” At the start of the summer, I landed a job behind the concessions kiosk at the Palladium, the movie theater at Bethel Mall just outside of Main Heights: the world’s easiest, stupidest job. Most days the whole mall is empty except for moms in spandex pushing baby strollers, and even when they come to the Palladium they never order anything but Diet Coke. All I have to do is show up and I get $10.50 an hour.

“I’m dead serious.” Mom folds her hands on the table, her knuckles gripped so tightly I can see every bone. “Your father and I think you need a little more structure this summer,” she says. Amazing that my parents can only find time to stop hating each other to team up against me.

“Something to keep you busy.”

Busy. Like stimulated, that word is parent-speak for: supervised at all times and bored out of your mind.

“I’m busy at the Palladium,” I say, which is a complete lie. “You mix butter into popcorn, Nicki,” Mom says. A crease appears between her eyebrows, as if someone has just pressed a thumb to her skin.

Not always, I nearly say.

She stands up, cinching her bathrobe a little tighter. Mom runs summer-school sessions Monday through Thursday. I guess since it’s Friday she didn’t bother getting dressed, even though it’s after 2:00 p.m. “I’ve spoken to Mr. Wilcox,” she says.

“No.” The itch has become a full-blown panic. Greg Wilcox is a creepy old guy who used to teach math at Mom’s school, until he chucked academia for a job managing the world’s oldest, most pathetic amusement park, Fantasy Land. Since the name makes it sound like a strip club, everyone calls it FanLand. “Don’t even say it.”

Apparently she isn’t listening.

“Greg said he’s short-staffed this summer, especially after...” She breaks off, making a face as if she’s sucking on a lemon, meaning she almost said something she shouldn’t have. “Well, he could use an extra pair of hands. It’ll be physical, it’ll get you outside, and it will be good for you.”

I’m getting pretty sick of my parents forcing me to do things while pretending it’s for my benefit.

“This isn’t fair,” I say. I almost add, You never make Dara do anything, but I refuse to mention her, just like I refuse to ask where she is. If she’s going to pretend I don’t exist, I can do the same for her.

“I don’t have to be fair,” she says. “I’m your mom. Besides, Dr. Lichme thinks...”

“I don’t care what Dr. Lichme thinks.” I shove away from the table so hard the chair screeches on the linoleum. The air in the house is thick with heat and moisture: no central air. This is what my summer will be like: instead of lying in Dad’s spare bedroom with the AC cranked up and all the lights off, I’ll be sharing a house with a sister who hates me and slaving away at an ancient amusement park solely attended by freaks and old people.

“Now you’re starting to sound like her, too.” Mom looks totally exhausted. “One is enough, don’t you think?”

It’s typical of Dara that she can become not only the topic of but also a force in the conversation even when she isn’t in the room. For as long as I can remember, people have been comparing me to Dara instead of the other way around. She’s not as pretty as her younger sister... shyer than her younger sister... not as popular as her younger sister . . .

The only thing I was ever better at than Dara was being ordinary. And field hockey -- like running a ball down a field is a great basis for a personality.

“I’m nothing like her,” I say. I leave the kitchen before Mom can respond, almost tripping on the stupid gardening boots in the hall before taking the stairs two at a time. Everywhere are signs of the unfamiliar, little details missing and others added, like several plastic gnome-shaped night-lights outside Mom’s room and nothing but a bare patch of carpet in the office where Dad’s favorite, ugly-ass leather chair used to sit, plus more and more cardboard boxes full of junk, as if another family is slowly moving in or we’re slowly moving out.

My room, at least, is untouched: all the books organized spine-out and the powder-blue coverlet nicely folded and my stuffed animals from when I was a baby, Benny and Stuart, propped up on my pillows. On my bedside table, I spot the framed picture of Dara and me from Halloween when I was a freshman; in it, we’re both dressed like scary clowns, and in our face paint, grinning, we look nearly identical. I cross the room quickly and turn the picture facedown. Then, thinking better of it, I slide the photograph into a drawer.

I don’t know which is worse: that I’m home and so much is different, or that I’m home and so much feels the same.

Overhead, I hear a pattern of creaks. Dara, moving around her attic bedroom. So she is home.

Suddenly I’m so angry I could hit something. This is all Dara’s fault. Dara’s the one who decided to stop speaking to me. It’s Dara’s fault I’ve been walking around feeling like I’ve got a bowling ball in my chest, like at any second it might drop straight through my stomach and spill my guts on the floor. It’s her fault I can’t sleep, I can’t eat, and when I do I just feel nauseous.

Once upon a time, we would have laughed together about Dad’s girlfriend, and Dara would have made up a mean code name so we could refer to her without her knowing. Once upon a time, she might have come to work with me at FanLand just to keep me company, just so I wouldn’t have to deal with scrubbing out old-person smell and little-kid vomit from the ancient rides all by myself, and we would have competed over who could spot the most fanny packs in an hour or drink the most Coke without barfing.

Once upon a time, she would have made it fun.

Before I’ve fully decided what I’m going to say to her, I head back into the hall and up the attic stairs. The air is even hotter up here. Mom and Dad moved Dara from the ground-floor bedroom to the attic in the middle of freshman year, thinking it would be harder for her to sneak out at night. Instead she started climbing out the window and using the old rose trellis as her own personal ladder.

Dara’s bedroom door is closed. One time after we had a fight she painted "keep out" in big red letters right on the door. Mom and Dad made her cover it over, but in certain lights you can still make out the words shimmering under the layering of Eggshell #12.

I decide against knocking. Instead I fling open the door like cops do on TV shows, as if I’m expecting her to jump out at me. Her room is a wreck, as always. The sheets are pulled halfway off the bed. The floor is piled with jeans, shoes, sequined shirts, and halter tops, as well as a covering, fine as leaves, of the kind of thing that accumulates at the bottom of a purse: gum wrap-

pers, Tic Tacs, spare change, pen caps, broken cigarettes.

The air still smells, faintly, like cinnamon: Dara’s favorite scent.

But she’s gone. The window is open and a breeze distorts the curtains, making ripple patterns, faces that appear and disappear. I cross the room, doing my best to avoid stepping on anything breakable, and lean out the window. As always, instinctively, my eyes go first to the oak tree, where Parker used to hang a red flag when he wanted us to come play and we were supposed to be doing homework or sleeping instead. Then Dara and I would sneak down the rose trellis together, trying desperately not to giggle, and run, holding hands, to meet him at our secret spot.

There is no red flag now, of course. But the trellis is swaying slightly, and several petals, recently detached, twirl on the wind toward the ground. I can make out the faint imprints of footsteps in the mud. Looking up, I think I see a flash of skin, a bright spot of color, a flicker of dark hair moving through the woods that crowd up against the back of our house.

“Dara!” I call out. Then: “Dara!” But she doesn’t turn around.

July 17

Dara

I haven’t climbed down the rose trellis since the accident, and I’m worried my wrist won’t hold. It got pulverized in the crash; for a month, I couldn’t even hold a fork. I have to drop the last few feet, and my ankles let me know it. Still, I’ve made it down in one piece. I guess all that PT is good for something.

No way do I want to see Nick. Not after what she said.

I’m nothing like her.

Perfect Nicki. The Good Child.

I’m nothing like her.

As if we didn’t spend practically our whole lives sneaking into each other’s rooms to sleep in the same bed, whisper about our crushes, watch moon patterns on the ceiling and try to pick out different shapes. As if we didn’t once cut our fingers and let them bleed together so we’d be bonded forever, so we’d be made not just of the same genes but of each other. As if we didn’t always swear that we’d live together even after college, the Two Musketeers, the Dynamic Duo, Light and Dark, two sides of the same cookie.

But now Perfect Nick has started to show some cracks.

The woods run up against another yard, neatly mowed, and a house staring at me through the trees.

Turning left will bring me past the Duponts’ house to Parker’s, and the hidden break in the fence that Nick, Parker, and I engineered when we were kids so we’d be able to sneak back and forth more easily. I turn right instead and get spat out at the end of Old Hickory Lane, across the street from the bandstand in Upper Reaches Park. There’s a four-person band onstage, of a combined age of about one thousand, dressed in old-fashioned straw hats and candy-striped jackets, playing an unfamiliar song. For a moment, standing in the middle of the road, watching them, I feel completely lost -- as if I’ve stumbled into someone else’s body, into someone else’s life.

There was one good thing about the accident -- and in case you’re wondering, it wasn’t the broken kneecaps or shattered pelvis, the shattered wrist and fractured tibia and dislocated jaw and scars where my head went through the passenger window, or getting to lie around in a hospital bed for four weeks and sip milkshakes through a straw.

The good thing was: I got to cut school for two and a half months.

It’s not that I mind going to school. At least, I didn’t used to mind it. The classes suck, sure, but the rest of it -- seeing friends, skipping out between classes to sneak cigarettes behind the science lab, flirting with the seniors so they’ll buy you lunch off campus -- is just fine.

School is only hard when you care about doing well. And when you’re the stupid one in the family, no one expects you to do well. But I didn’t want to see anyone. I didn’t want to watch everyone feel bad for me while I limped across the cafeteria, when I couldn’t sit down without wincing, like an old man. I didn’t want to give anyone an excuse to pity me, or pretend to pity me while feeling secretly satisfied that I’m not pretty anymore.

A car blares its horn, and I move quickly out of the road, stumbling a little on the grass, but grateful for the sense of strength returning: this is practically the first time I’ve left the house in months.

Instead of passing, the car slows, and time slows, and I feel a hard fist of dread squeeze in my chest. A beat-up white Volvo, its bumper attached to the undercarriage with thick ropes of duct tape.

Parker. “Holy shit.”

That’s what he says when he sees me. Not Oh my God, Dara. It’s so good to see you. Not I’m so sorry. I’ve been thinking of you every day.

Not I was afraid to call, so that’s why I didn’t.

Just: Holy shit.

“Pretty much,” I say, since it’s the only response I can think of. At that moment, the band decides to stop playing. Funny how silence can be the loudest sound of all.

“I’m . . . wow.” He shifts in the car but makes no move to get out and hug me. His dark hair has grown long and hangs practically to his jaw now. He’s tan -- he must be working outside, maybe mowing lawns again, like he did last summer. His eyes are still the same in-between color, not quite blue or green but something closer to gray, like the fifteen minutes just before the sun rises. And looking at him still makes me want to puke and cry and kiss him all at once. “I really didn’t expect to see you.”

“I live around the corner, in case you forgot,” I say. My voice sounds harder, angrier, than I’d meant it to, and I’m grateful when the band strikes up again.

“I thought you were gone,” he says. He keeps both hands on the steering wheel, squeezing tightly, like he does when he’s trying not to fidget. Parker always used to joke he was like a shark -- if he ever stopped moving, he would die.

“Not gone,” I say. “Just not seeing anyone.”

“Yeah.” He’s watching me so intensely I have to turn away, squinting into the sun. This way, he can’t see the scars, still angry and raw-red, flattened across my cheek and temple. “I figured -- I figured you didn’t want to see me. After what happened...”

“You figured right,” I say quickly, because otherwise I might say what I really feel, which is: not true.

He flinches and looks away, returning his attention to the road. Another car passes, and has to pull out into the oncoming traffic to avoid Parker’s car. He doesn’t seem to notice, even when the passenger, an old man, rolls down his window and yells something rude.

The sun is warm and sweat moves down my neck. I remember, then, lying between Parker and Nick last summer in Upper Reaches Park on the day after school ended, while Parker read out loud all the weirdest news he could find from around the country -- interspecies relationships; bizarre deaths; unexplained agricultural patterns that could only, Parker insisted, be caused by aliens -- inhaling the smell of charcoal and new grass and thinking, I could stay here forever. What the hell changed?

Nick. My parents. The accident. Everything.

I suddenly feel like crying. Instead I wrap my arms around my waist and squeeze.

“Listen.” He rakes a hand through his hair, which immediately swings back into place. “You need a ride somewhere or something?”

“No.” I don’t want to tell him that I have nowhere to go. I’m not heading anywhere except away. I can’t even go back for my car keys or I risk seeing Nick, who no doubt is finding reasons to complain about the fact that I wasn’t there to cheerlead her arrival.

He makes a face like he’s accidentally swallowed his gum. “It’s good to see you,” he says. But he doesn’t look at me. “Really good. I’ve been thinking about you... all the time, basically.”

“I’m doing just fine,” I say.

Good thing lying comes naturally to me.
