Some houses don’t just hold secrets. They hold everything.

When investigative journalist Quinn Mercer returns to her late sister’s Victorian estate on the Maine coast, she expects grief, paperwork, and a property that needs selling. She finds something else: a diary open to a page that shouldn’t exist, skeletal remains sealed inside a wall with modern dental work, and a pattern of disappearances stretching back sixty years, all connected to the house, all ruled voluntary departures, all involving the same family name on every permit ever filed.

Mara was investigating Greyhaven House before she died. She was very close to the truth.

Quinn is a rationalist. She doesn’t believe in ghosts. She believes in documentation, evidence, and the specific kind of institutional complicity that keeps small towns silent for generations. What she finds in Greyhaven House challenges all three, because some of what she experiences can be explained, and some of it cannot, and the difference between those two categories keeps shifting the closer she gets to the center of the pattern.

A slow-burn psychological paranormal thriller for readers who want their horror grounded, their investigations real, and their ambiguity earned.

Greyhaven House is the first novel in the The Blackwood Files.
