SUMMARY OF THE OVERNIGHT GUEST

True crime writer Wylie Lark doesn't mind being snowed in at the isolated farmhouse where she's retreated to write her new book. A cozy fire, complete silence. It would be perfect, if not for the fact that decades earlier, at this very house, two people were murdered in cold blood and a girl disappeared without a trace.

As the storm worsens, Wylie finds herself trapped inside the house, haunted by the secrets contained within its walls—haunted by secrets of her own. Then she discovers a small child in the snow just outside. After bringing the child inside for warmth and safety, she begins to search for answers. But soon it becomes clear that the farmhouse isn't as isolated as she thought, and someone is willing to do anything to find them.
