Inspired by a terrifying true story, acclaimed author Guadalupe Garcia McCall creates a twisty tale about a boy desperately trying to survive in a new town with a secret past.

James always knew moving from Texas to Oregon was going to be horrible..

But no sooner have he and his family arrived in their "perfect" new home in their "perfect" new town than he starts getting mysterious 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 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.
