On snowbound Mackinac, do the walls of the empty house whisper—or is his sanity starting to slip?
Would you uproot your life and move halfway across the country to spend a winter on a remote and sparsely populated island to be near the person you love? How about to be near a person you had a one-night stand with? While he doesn't want to admit it to anyone, much less himself, that's exactly what Clay has done after agreeing to dog sit for a family he doesn't know alone one winter on Mackinac Island.
It seems like a dream situation at first. Clay gets to live rent-free in a beautiful manor home out on the island's bluff, bank enough cash to pay off his mountain of debt, and have a chance to grow the spark he shared with Olivia, who he spent a night with over the summer while visiting the island. But it doesn't take long for Clay to realize he’s made a mistake. None of the inhabitants of the island seem to want him there, especially not Olivia, forcing him to spend almost all his time alone in the house. And it's becoming increasingly clear that he's not alone in the house.
Unsettling sights, sounds, and even smells torture him daily, and Clay's descent into madness is only halted by the appearance of a mysterious, beautiful woman who saves him with her nightly visits. Clay doesn't know if she’s a ghost, a guardian angel, or a figment of his imagination, but he slowly becomes wholly dependent, even obsessed, with this entity, which seemed to be her plan all along.
