The Light That Gets Lost — Natasha Carthew

A small boy hiding in a cupboard witnesses something no child should ever see. He tries not to look but he still hears it. And when he comes out, there's no mistaking. His mum and dad have been killed. And though he's only small, he swears that he'll get revenge one day.

Years later, Trey goes to a strange camp that is meant to save troubled teenagers. It's packed with crazies, god-botherers, devoted felons and broken kids. Trey's been in and out of trouble ever since the day the bad thing happened, but he's not here for saving: this is where he'll find the man who did it. Revenge and healing, salvation and hell are a boiling, dangerous mix, and Trey finds himself drawn to a girl, a dream and the offer of friendship in the dark...
