An eerie, twisty tale that is built around doubles.

American suburbia, the gated community of Herot Hall, nestled into a mountainside. Two little boys: Gren, who lives in a cave in the mountain, with some kind of ambiguous disfigurement that makes people afraid of him, and Dylan, who lives in Herot Hall in a life of luxury.

Two women: Gren’s mother Dana and Dylan’s mother Willa. They are the ones at the center of this story, and their battle is what carries the book to its climactic conclusion.
