Violet's grandmother had warned her about the Devil, had talked about him often, as though he were a best friend, or an old lover. But she never told Violet that the Devil could be real. She never told Violet that the Devil could be a dark-haired boy in vintage clothes who takes naps in the sun and likes old movies and vigilante justice.
River West is the seventeen-year old stranger renting the guesthouse behind the rotting mansion on the sea, where Violet lives. And as eerie things start happening in Violet's town, she begins to wonder about the boy living in her backyard. Is River just a crooked-smiling, coffee-loving liar with rascally eyes and a mysterious past? Or could he be something else? Something...evil?
Violet's already so knee-deep in love she can't see straight.
And that's just how River likes it.
