Showing Missing by Kelley Armstrong

Reeve's End is the kind of place every kid can't wait to escape. Each summer, a dozen kids leave and at least a quarter never come back. Winter Crane doesn't blame them - she plans to do the same in another year. She'll leave behind the trailer park, and never look back. All she has to do is stay out of trouble.

But then she has a chance encounter with a boy called Lennon, injured and left for dead in the woods. Her discovery has Winter questioning everything she thought she knew about her sleepy town. And when Lennon vanishes and his brother Jude comes looking for him, things take a sinister turn. Someone wants Winter out of the picture. Can she trust Jude? Or will he deliver them both into the hands of a stalker?
