Dungeon Crawler Carl Books in Order

Coast Guard veteran Carl is stuck with his ex-girlfriend's prize-winning show cat, Princess Donut, when every human-built structure on Earth collapses and sinks into the ground. The survivors are trapped inside an 18-level dungeon that circles the globe, forced to fight monsters and navigate traps for a sadistic intergalactic game show. Survival depends on entertaining alien viewers and building a following to earn loot drops.

The training levels have ended, and the games truly begin. Carl and his ex-girlfriend's cat, Princess Donut, enter the third floor of Dungeon Crawler World: the Over City, a ruined metropolis prowled by an undead circus. As murdered women rain from the sky and an ancient spell nears fruition, they must fight harder than ever to survive.

Carl and Princess Donut reach the fourth floor, a tangled railway maze where popularity has put prices on their heads. They must join other crawlers to solve the level’s puzzle while watching for betrayal. A forgotten manual may hold the key to unraveling the chaos.

They team with other crawlers to crack the floor’s puzzle, and Carl finds a dead anarchist’s manual, turning him from contestant into saboteur against the dungeon’s system.

Carl, Princess Donut, and Mongo reach the fifth floor of the dungeon, where they must capture four castles inside a single bubble within fifteen days to unlock the stairwell. This time they cannot manage alone and must cooperate with low-level crawlers trapped alongside them.

Carl and Princess Donut enter the sixth floor of the dungeon, a lush jungle called the Hunting Grounds where dinosaurs roam and tourists are permitted to hunt the remaining crawlers. A famed hunter named Vrah seeks the biggest trophy of her career, but the crawlers refuse to be prey. A mysterious celebration for the top crawlers, the Butcher’s Masquerade, awaits.

Management reels from the seventh level's conclusion as surviving crawlers reach the eighth floor and scatter. The map mirrors Earth's final days, where intangible ghosts of humanity relive their lives, unaware of doom. Monsters from Earth lore inhabit the regions. Teams must capture six legendary beasts to turn into battle cards before facing enemy decks.

On the ninth floor, Carl and his allies join Faction Wars as one of ten armies battling to capture a central castle.

Carl chafes under rules that strip his agency and secretly devises a dangerous plan he cannot share with anyone, because failure would mean consequences far beyond himself and Donut.
