Thirteen years after their mother's mysterious disappearance, Drew and Isaac Prescott receive a disturbing letter in the mail. It's an invitation to a reunion long overdue, signed by the missing woman herself.

Dangerously vague, the letter promises answers should Drew and Isaac be willing to make the journey.

Deep in the mountain wilderness, a secluded commune waits. It's a place of secrecy and superstition, where the locals regard the land as sacred, and revere the lake above all else.

Where Drew and Isaac will soon learn that while blood may be thicker... the water is frighteningly deep.

From horror author Abe Moss comes a chilling supernatural thriller about two siblings' harrowing struggle to escape the roots of their past. For fans of T. Kingfisher, Ania Ahlborn, and Adam Nevill's The Ritual.
