Inspired by the true story of the "Westfield Watcher,.” The first letter turns up on his desk. The second is stuck between the spokes of his bike. The third flies through the kitchen window. And they are all addressed to James from someone called the Keeper. Moving from Texas to Oregon was a bad idea. No sooner have James and his family arrived in their “perfect” new town than he starts getting mysterious and sinister letters from someone called the Keeper. Someone who claims to be watching him. Someone who is looking for “young blood.” James and his sister, Ava, are obviously in danger. But the problem with making a fuss about moving and having a history of playing practical jokes is that no one believes James—not even his parents. Now James and Ava need to figure out who is sending the letters before they become the next victims in their neighborhood’s long history of missing children. Because one thing is clear: uncovering the truth about the Keeper is the only thing that will keep them alive.
