Dr. Riley North finds comfort in the quantifiable. Her world is one of sterile labs and cold, hard data, a fortress of logic she built to escape the chaotic legacy of her parents—two cryptozoologists who vanished in the Oregon wilderness twenty years ago.

She believes that chapter of her life is sealed. But a phone call about an abandoned storage unit changes everything.

Inside the dusty locker, Riley discovers her parents weren't just chasing myths. They were methodical scientists on the verge of a world-shattering discovery. Their worn journals, detailed maps, and a final, chilling cassette tape labeled ECHOES reveal a trail of evidence—and a conversation with something impossibly real.

Drawn by a need for answers, Riley follows their final path into the unforgiving Kalmiopsis Wilderness. She’s not looking for a monster; she's hunting for a data point to close the case forever. But the deeper she goes, the more the forest pushes back. The silence is unnatural, the evidence she finds is terrifying, and the feeling of being watched is constant.

She soon discovers that the legendary creature is not the only thing hiding in the deep woods. The forest has other guardians, and not all of them are willing to let its secrets go. To solve the mystery of her parents' disappearance, Riley must survive the truth. But in a place this dark, some discoveries aren't meant for the world of men.
