As "Twilight" gets ready to ride off into the sunset, yet another young-adult supernatural book series is hoping to scare up some business at the box office.

Variety reports that Cassandra Clare's best-selling "The Mortal Instruments" series will be adapted for the big screen, with the goal being a possible film franchise.

Screen Gems is currently focusing on the first of Clare's four books, "City of Bones," which tells the story of Clary Fray, a redheaded 15-year-old Manhattanite whose mother suddenly goes missing. Searching the city, Clary encounters supernatural creatures including demons, werewolves, and vampires.

Over the course of the series, Clary also finds herself caught in a love triangle with dark-haired bloodsucker Simon Lewis and blond Shadowhunter/angel hybrid Jace Wayland.

Hmmm… sound familiar?

Maybe, but author Clare says there is a big difference between her characters and those of Stephenie Meyer. She told Teen Libris, "My vampires are allergic to crosses and sunlight, can't go into churches, [and] fear holy water."
