The gang thought they were done with murder.

After surviving one too many mysteries, they’re finally ready for a normal summer —until Chillshore reopens. Once a beloved island theme park, it shut down after a tragedy no one ever fully explained. Now it’s back and rebranded as a spooky attraction that leans hard into its dark past, complete with a creepy mascot known as the Groundskeeper and a guest list that includes horror influencers, true crime celebrities, and supernatural thrill-seekers.

Then a storm hits. No boats. No phones. No escape.

When guests start dying one by one, it becomes terrifyingly clear that the murders aren’t random. Each death exposes a piece of Chillshore’s buried history.

As paranoia spreads and the Groundskeeper stalks the island, the gang must untangle a web of lies, cover-ups, and long-suppressed guilt before the killer strikes again. Because this time, the mystery isn’t just about who is doing the killing — it’s about why the truth was buried in the first place.

Dark, twisty, and relentless, Bill Wood’s final installment in the Let’s Split Up trilogy delivers a blood-soaked locked-room mystery that confronts the cost of turning real tragedy into entertainment and proves some stories will always come back to haunt you.
