The retreat promised healing. The forest demanded something else.

Duncan arrives at a secluded forest retreat hoping to escape the guilt that has consumed his life. Hidden deep in the British wilderness, the program promises healing for damaged men through therapy, isolation, and a chance to begin again.

But the retreat is unlike anything Duncan expected.

As therapy gives way to strange rituals, the forest itself seems to awaken. Duncan forms an uneasy bond with another participant, Adam, while an unseen presence begins to weave itself through the trees—and through the men themselves.

When the retreat ends, none of them remembers leaving.

Twelve years later, the survivors are dying one by one in impossible, violent ways.

To stop whatever followed them home, Duncan and Adam must return to the forest they can't remember...and confront the darkness waiting beneath its canopy.

Because the forest never forgot them.

Perfect for readers who love psychological horror, folk horror, cult mysteries, creeping dread, and stories where the darkest monsters are born from human trauma.
