'Mortal Instruments: City Of Bones' Poster: The Best Of Both Worlds

Pack your black—we're heading deep into the "City of Bones."

The first trailer for the big-screen adaptation of Cassandra Clare's best-selling "Mortal Instruments" novel won't hit the MTV interwebs until later tonight at 10:30 ET, but we have something for you to ogle in the meantime: namely, the film's first one-sheet!

Utilizing a dazzling reflective image, the poster cleverly depicts the film's dual settings: New York City and the titular City of Bones, where the Shadowhunters' most wise and powerful, know as the Silent Brothers, reside, and where heroine Clary Fray retreats to seek answers to her family's complicated past—and present.

Check out the full poster and synopsis after the jump!

Set in contemporary New York City, a seemingly ordinary teenager, Clary Fray (Lily Collins), discovers she is the descendant of a line of Shadowhunters, a secret cadre of young half-angel warriors locked in an ancient battle to protect our world from demons. After the disappearance of her mother (Lena Headey), Clary must join forces with a group of Shadowhunters, who introduce her to a dangerous alternate New York called Downworld, filled with demons, warlocks, vampires, werewolves and other deadly creatures. Based on the worldwide best-selling book series.

In addition to the "City of Bones" trailer, MTV News will be rolling out a slew of "TMI" content this week, including a trailer commentary with author Cassie and an interview with director Harald Zwart. So be sure to stick close for all things Shadowhunter!
