There’s LitRPG, and then there’s Dungeon Crawler Carl. In fact, Matt Dinniman may have forever ruined this genre for me, as I don’t think I’ll ever find a series as fun and amazing. The Gate of the Feral Gods is the fourth installment, but there’s no slowing down here. Instead, we’re charging full steam ahead, plunging deeper into the chaos!

The story picks right up from where things left off in The Dungeon Anarchist’s Cookbook, joining Carl and his larger-than-life feline companion, Princess Donut, as they descend deeper into the dungeon in their continued fight for survival. Now on the fifth floor, the rules shift dramatically, presenting an entirely new set of challenges. This level introduces a unique twist: all crawlers are separated into individual biome-themed “bubbles” which are scattered across four quadrants of the game world. Unfortunately for Carl and Donut, this means being cut off from their friends, and to make matters worse, they won’t be able to access the next floor until all the objectives in their bubble are met. As this is not something they can do on their own, success hinges upon finding new allies—and fast.

By now, we’re starting to see a pattern emerge, with each level introducing a distinct gaming mechanic. In many ways, the fifth floor mirrors an epic game of Capture the Flag, in which crawlers are randomly assigned to the different bubbles, such as air, water, land, and deep ocean. Each biome also features their own set of dangers, mobs, and goals. The only way to break free is to destroy the castles in their respective bubbles, which would then allow crawlers to assist others in doing the same. But of course, Carl, Donut, and their new party member Katia have landed in one of the toughest bubbles, where the challenges are more difficult and the odds against them are stacked higher than ever. Still, as we all know, it will take much more than that to break their spirit.

The Gate of the Feral Gods was yet another fantastic sequel, and I just love cracking open each book to discover what awesome adventure awaits us next. What makes these books so addictive and so entertaining is the way each volume builds upon the ones that came before, driving up the excitement while still maintaining the humor, heart, and thrilling action. These books are laugh-out-loud funny, and I’m always surprised at Carl’s ingenious solutions to seemingly impossible situations. I’m also floored by the sheer creativity in everything from small-scale puzzles in the dungeon to the overarching intrigue of who or what in the great wide universe is actually in control of the crawl.

It’s honestly impressive how Dinniman can manage to juggle so many moving pieces of the storyline all at once. You’ve got multiple character arcs unfolding simultaneously, all their interconnected plotlines, a dungeon and its AI that are constantly shifting in new and unexpected ways, various RPG mechanics that are expanding as the characters get stronger, plus an intergalactic political drama playing out in the background to boot! Whew! With so much happening at once, one thing for sure is that you’ll never be bored, and what’s more, each storyline is given the time and attention it deserves. True, sometimes things can feel a little overwhelming, but so far, the author seems quite diligent in resolving story threads so that readers aren’t left hanging.

But truly, what sets Dungeon Crawler Carl apart is its character development. Yes, we get new quest lines, new boss fights, and plenty of the crazy-ass dungeon-crawling mayhem that can only come from the mind of Matt Dinniman, but we also get to see Carl and Donut’s relationships evolve—both with each other and with the ever-expanding cast of allies and adversaries. In some ways, this series has the feel of a favorite soap opera, where I just can’t wait to dive back in to catch up with all the characters.

That said, things get pretty bleak for some of them. It’s a sad fact that none of the side characters are truly safe, and even Carl and Donut get put through the wringer, as they adapt to increasingly cruel and brutal challenges. Our protagonist has repeatedly sworn that the dungeon will not break him, but with each new level, the physical and psychological toll on him only seems to get worse. Still, whenever circumstances start to look dire, there’s always much needed levity to pull us out—often thanks to Donut and her impeccable talent for saying the most absurd things at the most inopportune times.

When all is said and done, I think The Gate of the Feral Gods might be my favorite book of the series so far, delivering on every front and exceeding expectations in every way. This book has everything readers love about Dungeon Crawler Carl—pulse-pounding action, gut-busting humor, and surprisingly deep emotional moments—all wrapped up in an explosive plot that’s impossible to put down. It’s a must read for fans, obviously. And if you haven’t started this series yet, don’t wait! With the re-issuing of all the books, there’s no better time to jump in.
