It was a warm evening in September when twelve-year-old Danny Yates came back from the dead. He walked into town half-starved and silent, ten months after he and his best friend Will Keefe were presumed drowned. And when Danny does finally speak, he swears that he's not Danny. He's Will. Danny's mother is convinced that her only son has come back wrong, that he is a monster wearing the face of her child. Chief of Police John Deacon is more interested in how the abduction of two boys could have been written off as a tragic accident, and who was responsible. What happened to Danny to make him take on his friend's name, his personality? And does Danny's return mean there's a chance that Will is still alive?
