The Overnight Guest by Heather Gudenkauf is the kind of thriller you'll devour in one sitting. True crime writer Wylie Lark doesn't mind being snowed in at the remote farmhouse where she's writing her latest book. Yes, it was the site of a double murder decades earlier, but she's certain the past can't hurt her. Then a small child appears out in the snow. After Wylie brings the child inside, her troubles begin. It quickly becomes clear she's not as alone as she thought she was, and the history of the house may be coming back to haunt her after all.
