Run (The Hunted #1)

Sixteen-year-old Reid thinks life is back to normal. His sister Lucy pulls herself together and cuts him free from a year of foster care. She promises to take care of him, that her new boss and her new life are what they both needed to start again. Until Reid is taken in the middle of the night, dumped in a wild stretch of forest far from home with no idea why he is there. Lost and afraid, he learns to run from the hunters who prowl the darkness, their only pleasure chasing down kids like him. And killing them.
