Dungeon Crawler Carl #4

Chaos Inside the Bubbles

The Gate of the Feral Gods sends Carl, Princess Donut and Mongo into a fifth-floor challenge built around four deadly castles and a shrinking deadline.

Matt Dinniman’s fast-paced mix of LitRPG strategy, dark comedy and escalating danger keeps the adventure propulsive, with team dynamics giving the spectacle greater emotional weight. The expanded cast and increasingly complex dungeon mechanics reward readers already invested in the series, leading to a chaotic, funny and genuinely affecting fourth installment.

A Backlist With Blockbuster Energy

Dungeon Crawler Carl follows a former Coast Guard officer and Princess Donut, his ex-girlfriend’s newly intelligent cat, through an alien-controlled dungeon broadcast as a galactic reality show.

The edition reviewed here is Ace’s 2025 hardcover republication of the fourth book, originally self-published in 2021. The series currently extends through book eight, A Parade of Horribles, which became a number-one New York Times bestseller in May 2026. Its backlist has shown unusual staying power: five different volumes appeared simultaneously within the top 15 hardcover fiction titles in July 2026, years after their original publication.
