__ siempre había escuchado rumores sobre Jeff: un chico de sonrisa extraña, temperamento explosivo y una presencia que hacía que todos guardaran silencio. Ella pensaba que lo entendía, que podía seguirle el paso y ganarse su confianza.

Pero cuando llega a un lugar aislado donde las noches parecen no terminar, __ descubre que Jeff no es el único secreto. Hay personas que desaparecen, mensajes que aparecen en las paredes y alguien que observa cada uno de sus movimientos.

Para sobrevivir, __ tendrá que decidir si quiere acercarse a Jeff, enfrentarlo… o descubrir quién está intentando separarlos.
