Frank Peniston is going clean.

No more Full Throttle. No more caffeine-fueled hallucinations. No more infinite ammo shootouts on an empty stomach. Just a solo detox retreat at an abandoned lighthouse full of ghosts, curses, eldritch sea gods, haunted vending machines, and something called the Crab Pope.

When Frank and his faithful (and increasingly unhinged) sidekick Ronald uncover an ancient bottle with cursed runes, they accidentally awaken something wet, undead, and aggressively nautical. What starts as a caffeine cleanse spirals into a brine-soaked showdown involving drowned cultists, reverse-lit beacons, whispering conch shells, possession via Arby's Latin, and a final battle powered by forbidden soda.

Also, Frank gets a foot removed.

From the unfiltered mind of Frankfort Petersén, Book 6 in the Frank Peniston Mystery series is part cosmic horror, part action comedy, part very messy intervention.

Because sometimes, rock bottom is a lighthouse.

And it bleeds.
