by Jenny Valentine
When the sixteen-year-old runaway Chap is mistaken for a missing boy named Cassiel, his life changes dramatically. Chap takes on Cassiel's identity, gaining the family and friends he's always dreamed of having. But becoming someone else isn't as easy as he hoped - and Chap isn't the only one hiding a secret. As he teeters on the brink of discovery and begins to unravel the mystery behind Cassiel's disappearance, Chap realizes that he's in much deeper danger than he could have imagined.
After all, you can't just steal a life and expect to get away with it.
Award-winning author Jenny Valentine delivers an explosive mystery where dark secrets, betrayal, and loss pave the way for one teen's chance at redemption.

"Starred Review. Readers who like the quick pace of Gail Giles' mysteries and the dark, finely crafted suspense of Kevin Brooks will find the perfect combination here." - Kirkus Reviews
"Some of the twists are a little unbelievable, but the slow series of revelations, coupled with Valentine's incisive exploration of identity and perception, add up to the kind of tense, nerve-wracking story that teens will race to finish." - Publishers Weekly
