Flynn, a quiet but determined young man, lives in an underground road tunnel with thousands of others. The world outside is a wasteland, and the radiation of the sun can mutate genes. But Flynn has a secret: he himself has a hidden mutation, an erratic ability to kill with his mind. When a woman finds Flynn claming there are others like him, with strange and powerful mutations, he must make a choice—does he continue to live in the shadows, or will he risk his life to save his own kind? One thing is certain: if he fails, there will be retribution. The path to freedom is fraught with danger. Everyone he loves may die.
