Overview (Spoiler-Free)
Courtney Gray is looking forward to a peaceful family vacation at a secluded lake resort in the Northwoods of Wisconsin. The trip brings together two families — Courtney’s brother, his wife, and their two children, along with Courtney’s own family. The setting feels idyllic at first: quiet cottages by the water, fresh air, and time away from everyday stresses.
That peace shatters one morning when Courtney hears a blood-curdling scream from the neighboring cottage. She rushes over and discovers her brother and sister-in-law brutally murdered. Her young nephew Wyatt is found asleep upstairs, unharmed. But her teenage niece Reese is missing.
As police swarm the resort and the investigation begins, dark secrets start surfacing — not just about the families involved, but about the town itself. Everyone seems to be hiding something. The more Courtney digs, the more she realizes the crime is far more complicated than it appears. Questions swirl: Is Reese a victim who was taken… or is she somehow involved? And what other hidden truths about the families and the resort will come to light?
The story unfolds through dual timelines and multiple points of view, building tension as the investigation deepens and long-buried family secrets threaten to destroy what remains of the families.
