One Last Scare by Bill Wood (Paperback)

The past comes back to kill. The final, blood-soaked instalment in Bill Wood’s Let’s Split Up trilogy — a dark, twisty YA locked-room mystery, from the author behind the biggest-selling YA debut of 2024.

When Cam, Jonesy, Amber and Buffy are invited to experience a brand-new theme park called Chillshore, the gang jump at the chance of some downtime together. A remote island, a few rides, no gruesome murders or mysteries to solve in sight. Right? Wrong. Once a beloved island attraction, Chillshore shut down after a tragedy no one ever fully explained — and now it’s reopened, 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 of 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 the murders aren’t random: each death prises open another piece of Chillshore’s buried history. As paranoia spreads and the Groundskeeper stalks the island, the Sanera Four must untangle a web of lies, cover-ups and long-suppressed guilt before the killer strikes again — because this time, the real question isn’t just who’s doing the killing, but why the truth was buried in the first place.

A relentless mystery about the cost of turning real tragedy into entertainment.

Perfect for readers who love twisty YA horror, slasher-style locked-room mysteries, a tight-knit friend group under threat — and anyone ready to see the Let’s Split Up trilogy to its blood-soaked end.
