By Matt Dinniman · Narrated by Jeff Hays · 704 pages in hardcover · First released May 12, 2026

Book 8 of Dungeon Crawler Carl by Matt Dinniman. A Parade of Horribles covers Floors 10 and 11 -- the racing floor, the coming-out party for the ages, at 704 pages in hardcover. Narrated by Jeff Hays. Released May 12, 2026.

The setup

Floor 10 is a racing floor. Finish each race, never finish last, and upgrade your vehicle between rounds while the tracks get meaner. For this dungeon, that is suspiciously ordinary.

The glitches are not ordinary, and they keep getting more frequent.

Neither is the eleventh floor. The System AI calls what waits there "a coming-out party for the ages," and the publisher's description says not even the showrunners know what that means.

Everything is fine, Crawler. We repeat, everything is fine.

What we know

• 704 pages in the Ace hardcover (Book 7, at 880, is still the longest)
• Covers Floor 10 AND Floor 11
• Vehicle-based racing format with upgrades between rounds
• Increasing system glitches
• The AI has plans for Floor 11 that nobody -- not even Borant -- understands
• Carl has a plan of his own. The publisher's description: "It's a plan so dangerous, so insane, he can't even consult his friends lest the AI put a stop to it."
• The publisher's description, in full System AI voice: "The stakes are higher than they've ever been. No. The stakes are higher than they've ever been."

Before you start Book 8

Who is still in the crawl when Book 8 opens depends on how Book 7 ends, so that stays off this page. Need a refresher first? The Book 7 recap covers Book 7, ending included, and the Where Was I tool finds the right catch-up for the last book you read.
