Nine month ago Eden Wallace became a widow and she’s still grieving. She’s incapable of sleeping, her grief has alienated her friends and family, and she’s developed a paralyzing fear of the dark. She spends her days restlessly mourning and her nights burning every light in her house to keep the darkness at bay. The insurance money is running out and, even though it is hard, she knows it’s time to get on with her life. She just doesn’t know how.
Then she finds the reservations. A seven day stay in the guest house at Straits Point International Dark Sky Park, an astronomical preserve, near Mackinac Island in Michigan, far removed from urban light pollution, perfect for star gazers. Neither of them were astronomers and Eden didn’t think her husband had been much of a planner, but it seemed he had planned a secret, romantic, anniversary getaway for them sometime before he died.
So there’s the plan. Spend a week alone coming to terms with the loss of her husband, confronting her phobia, and returning home ready to restart her life. There’s only one problem. She won’t be alone. It turns out the guest house is built for communal living and she’s sharing it with a group of friends intent on a sort of college class reunion.
Dev, Paris, Sam, Martha, and Hillary aren’t any happier to be sharing the house than Eden is. But Malloy, the golden boy of the group, welcomes her with open arms. Despite his friendliness, Eden’s plan are shot. She’ll stay the night (in her brightly lit suite) and, as soon as the sun is up, head home to continue her bereaved half-life as long as she can.
That’s the new plan… until a scream rings out in the middle of the night. Malloy’s been murdered, his body found in the kitchen. A screwdriver protruding from his neck.
Now, Eden is stuck with the surviving friends, each a suspect and each with a secret motive for wanting Malloy dead. Eden just want to get home, but the small town police force doesn’t seem prepared to investigate a crime of this magnitude. They have found one thing though; a latent hand print in the guest house, a print belonging to Eden’s dead husband.
