Cul-De-Sac (Behind the Wall, #1)

Jacob Hines is thrust into a world that can't exist. After the horrific death of his parents and being accused of the crime, Jake is finally released into the custody of grandparents he never knew existed. If they're his grandparents at all. Which doesn't matter, because he has a secret. A thing that must never be spoken of at all. Even if the strange walled community he finds himself in is actually a prison. Even if he's going to be killed to keep secret what he holds inside of himself, behind the walls of his mind.
