Why he wrote it

Pulling the lens back in

Book seven, ‘This Inevitable Ruin,’ sent Carl and his companions sprawling across the dungeon in a total-war story with a wide ensemble and an open map. By the time Dinniman was planning book eight, he knew the series needed to contract before the endgame could begin, and the racing floor on level ten was the structural device he built that contraction around.

Matt Dinniman

It’s kind of a strange juxtaposition to the previous book, which is a big war novel, total war style book and it’s very, very hyper focused on Carl and Donut, which the previous book it wasn’t. It’s a bit of, um, narrowing of the focus of the lens and I really wanted to make sure that happens before we get to like the, the climax of the series. [paraphrased from audio — Lits Play]

Narrowing the focus meant making a design choice he expected readers to resist. The floor’s elimination races, where the last-place team is cut after each round, are structured so Carl cannot do what he does best: find cracks in the system and exploit them. Dinniman built that constraint in on purpose, and he knew it would cost him goodwill with an audience used to watching Carl improvise.

Matt Dinniman

I wanted to write a book where Carl didn’t have any agency, and that was difficult to get through because I knew people weren’t gonna vibe with that because the previous book was open world and you can do whatever you wanted. And then I wanted to open it up as wide as possible at the end of book eight. [paraphrased from audio — LitRPG Con interview, Maude Garrett]

By the time he was drafting the book, the scale of his readership had become its own kind of pressure. More than a million people were following the series, and some of them had told him, at signings, that waiting for the next book was the reason they were still alive.

Matt Dinniman

I have people tell me that they’ve been suicidal, and they’re putting off killing themselves because they’re waiting for my book. And that’s a lot of pressure — that’s weight on my own mental health. And I can understand other authors just crushing under that weight. And for me personally, I can’t wait to sit down and write. I can’t wait to get these words out. So it affects me greatly, but it doesn’t affect my output, if that makes sense.

How he wrote it

Racing without a map

The floor’s elimination structure, in which survivors choose an upgrade after each race and the next track gets harder, came from genres Dinniman had grown up with rather than from literary precedent. He drew the scaffolding from two sources and let the built-in escalation pace the book for him.

Matt Dinniman

kind of a mix of like the Hanna-Barbera Wacky Races and then like games like Mario Kart [paraphrased from audio — Lits Play]

That escalation structure also solved a problem Princess Donut had created. By book eight she is powerful enough to flatten most threats with a single spell, so Dinniman designed challenges at the puzzle level rather than the power level, putting himself and his characters in situations he personally could not solve and finding the exit in the moment.


Raising the stakes above book seven’s war-novel scale while simultaneously tightening the focus onto two characters was the kind of contradiction that slowed the whole project down. He was speaking ahead of the book’s May 2026 publication when he described where that tension landed.

Matt Dinniman

Book 7 had such a big set piece. It was such a big explosive story. Raising the stakes past Book 7 while focusing the story itself becomes extremely difficult to do. And that was the biggest challenge. It was very fun to write, but at the same time, it took me a little bit longer than usual to write this book because it was difficult for me to find my footing in terms of how I should present the story. But I think in the end, I came up with a pretty good balance because it starts off very narrow and it ends like the most bonkers ending I’ve ever written on anything I’ve ever written.

A Mr. Rogers quote sits at the opening of the book. Dinniman did not choose it as decoration: he used it as the lens through which every subsequent decision about character and theme was made.

Matt Dinniman

That particular quote, that’s at the beginning of book eight, A Parade of Horribles, and becomes the theme of that book, where it’s sometimes the people who are behind the scenes — the ones you don’t necessarily see — who are the ones truly propping everything up.

His first draft came in at 235,000 words. Penguin Random House asked for something shorter, and he agreed on the condition that book nine would have more room. The final version landed around 200,000 words, a concision he partly attributes to the floor itself rather than just editorial pressure.

Matt Dinniman

it’s a non-Scolopendra floor. So there’s less — I don’t want to say less story tickering, because something very major happens at the end of it. But it was always going to be a little bit shorter, I think.

Dinniman works without outlines, writing into situations he cannot see his way out of and finding the solution as the draft moves forward. The ending of ‘A Parade of Horribles’ is the most extreme product of that method in the series: he described it before publication as the wildest thing he had ever written, and after the book came out he confirmed it had genuinely caught him off guard.

Matt Dinniman

It’s a bit of a surprise ending that even not surprised even me because I wasn’t planning on doing that. [paraphrased from audio]

What he wants us to sit with

You are not in it alone

Carl, the series’ protagonist, has spent most of eight books planning in isolation: keeping secrets from allies, absorbing losses privately, treating self-sufficiency as survival strategy. The Mr. Rogers framing that opens the book exists because, for the first time in the series, that posture starts to visibly cost him something.

Matt Dinniman

Carl starts to realize that as well. It’s subtle, but he starts to realize he can’t do this all on his own. There are so many people in this situation with him who are helping him survive, and some of them are getting lost and forgotten along the way. That’s going to take a heavy toll on him as a character and Donut as well. But it’s also heartening to look back. That’s the purpose of that original quote: When you’re scared, to look and see what else is out there, see you’re not in it alone.

The dungeon in the series runs on a system intelligence that stages and broadcasts the crawl as entertainment for alien audiences. By book eight, readers familiar with the series might assume that AI is Dinniman’s stand-in for contemporary algorithmic systems. He pushes back on that reading directly, explaining what the dungeon AI is and what it is not, and pointing to ‘Operation Bounce House,’ published the same year, as the place where his real-world concerns about gamified atrocity live instead.

Matt Dinniman

The AI in ‘Carl’ is a different sort of thing. It’s not the same sort of AI that’s affecting our lives today. That’s going to be abundantly clear in Book 8, it’s a completely different thing.

With eight books written and two to go, he also offered a navigational image for where the series stands: ‘We’re past the arc of the arrow. We’re on the way back. I kind of see where the arrow is going to land.’ The descent has begun, and ‘A Parade of Horribles’ is the moment readers feel the trajectory change.
