Dungeon Crawler Carl: Start Here for litRPG (And Yes, the Cat Matters)

September 8, 2026

The title is the worst thing about this book.

Dungeon Crawler Carl. It sounds like something in a spinner rack next to the beef jerky. I skipped it twice. A guy on my crew named Ray would not let it go — brought it up at coffee, brought it up at lunch, brought it up while we were hanging a door — so I finally read the first chapter on my phone to get him off my back. Then I sat in my truck in a Canadian Tire parking lot with the heater running for forty minutes, because I didn’t want to stop.

So consider this me being Ray.

The premise, told straight

Carl is twenty-seven and out of the Coast Guard. It’s a cold night in Seattle and his ex-girlfriend’s cat has gotten out, so he goes after her in his boxers, a leather coat, and a pair of pink Crocs. The cat is a champion Persian named Princess Donut. She is not his cat. He goes anyway, and that one decision — going out into the cold for something that isn’t even yours — is basically the whole man in a sentence.

While he’s out there, every building on Earth disappears.

Not blown up. Taken apart, on purpose, by an alien company that decided our raw materials were worth more than our cities. Everyone indoors is gone in an instant. The people left standing outside get told the new rules: there’s a dungeon under the ground now, eighteen floors deep, and going down is the only option that isn’t dying up here.

And it’s a game show. The whole thing is broadcast live to an audience of aliens who think we’re a riot.

Carl goes down the stairs barefoot, because pink Crocs are not armor. That detail turns out to matter more than you’d think.

The jokes are holding weight

Here’s what nobody tells you about this book, and it’s the reason I bother writing about it.

It’s very funny. It is also, underneath, about a regular guy who lost his whole world and his girlfriend and his apartment and every person he knew, and who decides — on camera, for the entertainment of strangers — to keep being decent about it. Nobody makes him. There’s no reward for it. He does it anyway, and he’s tired, and he keeps doing it.

I did not sign up for feelings. I got feelings, in a book about a talking cat.

That’s the trick Dinniman pulls off. The comedy isn’t a coat of paint over a serious book, and the serious part isn’t a lecture hiding in a comedy. They’re the same thing. A joke lands and then two pages later the same joke costs somebody something, and you sit there going, oh. That was set up eighty pages ago.

The other thing worth saying plainly: it’s a book about being watched. Everything Carl does gets rated, sponsored, clipped, and monetized by an audience that wants him hurt in entertaining ways. That’s a 2010s indie web serial that has aged into something uncomfortably familiar. I don’t think it’s trying to be a statement. It just is one, on the way past.

Donut earns her billing

I want to be careful here, because “there’s a funny talking cat” is exactly the kind of thing that makes a person put the book back down.

Princess Donut eats an enchanted biscuit early on and comes out of it able to talk. She has enormous charisma, in the literal scored-by-the-system sense, and it makes her the party leader — which means Carl, the actual fighter, works for the cat. She is vain. She is dramatic. She is completely convinced she is the star of the broadcast, and the infuriating part is that she’s right.

But she isn’t a gag that got promoted. Donut is genuinely good at this. She reads the audience better than Carl does, she’s a real threat in a fight by the back half, and the relationship between the two of them does the quiet work of the book — two survivors of the same bad night, stuck together, learning to actually like each other. My wife Dee read one chapter over my shoulder, laughed at Donut, and then asked me two days later if the cat was okay. That’s the book working.

Who’s going to bounce

I’m not going to pretend everyone should read this.

It’s crude. There’s swearing on most pages, there’s gore, and there’s a running bit about the system’s very strange interest in Carl’s bare feet that some people find hilarious and some people find exhausting. Nothing is dwelled on in a nasty way, but if you want a clean read, this is not your clean read.

The other honest warning: people die, including people you’d rather didn’t, and the deaths aren’t tidy. This is a story about a slaughter played for ratings, and it doesn’t cheat by keeping the camera off things.

Skip it if you want gentle. Skip it if a stat screen in the middle of a chapter is going to break your immersion — there are numbers on the page, and they’re part of the fun, but that’s a taste thing and I’m not going to argue you out of it. And skip it if you’re the reader who needs a book to be about something announced up front. This one earns its meaning late.

If none of that scared you off, you’re in.

The distraction test

Every book I write about here gets the same rating, which is not sophisticated: does it survive real life?

I read a chunk of this one at the kitchen table at 5am with coffee, before anyone else was up, which is the easy condition. I read the rest in the stands at a cold rink during a Saturday skate, with a seven-year-old going down every ninety seconds and a nine-year-old scoring each wipeout out of ten. I lost my place twice. Found it in seconds both times, because this book is built in short, punchy chunks — a fight, a message from the system, a fresh problem — so you can drop back in anywhere without rereading half a page to remember who’s talking.

That’s the whole case for it as a winter book, honestly. It doesn’t punish you for having a life happening around it, and it’s exactly the thing you want when you’re killing forty minutes in a warm truck waiting on someone.

Start here

If you’ve been curious about litRPG and don’t know where to get on, this is the on-ramp. It’s the one I hand people. It’s the one that got me, and I went in rolling my eyes harder than you are right now.

Read the first chapter. Just the one. The title still won’t do it any favors, and the first chapter will.

The hardcover from Ace is the nice one to own, with a maze printed on the case under the jacket, which delighted me more than I’m prepared to defend. Plenty of folks do this series on audio instead, and that’s a completely legitimate way in — long drives, a shop, a fence to paint. Either way, start with book one. The rest of the shelf isn’t going anywhere.
