A standalone horror novel from #1 New York Times bestselling author Kelley Armstrong. Laney Kilpatrick has been renting her vacation home to strangers. The invasion of privacy gives her panic attacks, but it’s the only way she can keep her beloved Hemlock Island, the only thing she owns after a pandemic-fueled divorce. But broken belongings and campfires that nearly burn down the house have escalated to bloody bones, hex circles, and now, terrified renters who've fled after finding blood and nail marks all over the guest room closet, as though someone tried to claw their way out...and failed. When Laney shows up to investigate with her teenaged niece in tow, she discovers that her ex, Kit, has also been informed and is there with Jayla, his sister and her former best friend. Then Sadie, another old high school friend, charters over with her brother, who’s now a cop. There are tensions and secrets, whispers in the woods, and before long, the discovery of a hand poking up from the earth. Then the body that goes with it... But by that time, someone has taken off with their one and only means off the island, and they’re trapped with someone—or something—that doesn’t want them leaving the island alive.
