I've read (or Listened) to a lot of these Dungeon Books. I like the genre, but at a certain point, the amount of them coming out starts to overwhelm. Now, you have to ask what is this new series doing differently? What new idea is it bringing to the table?
Because at some point, just having different adventurers wander into the Dungeon gets repetitive and old fast.
Some Dungeon books have tried to change this up by making the Dungeon master a pervert or bad guy (Lewd Dungeon, Corrupt Dungeon, Brutal Dungeon). A lot of others quickly turn the Dungeon into the first step of Empire Building (Dungeon Deposed, CONQUEST: The Dungeon Core Gambit, etc).
Basically, a new Dungeon series needs a gimmick to stand out. This one's gimmick is that the Dungeon's entrance moves around. First to a Dwarven Realm, then to a Kobold tribe, then to Human lands. What makes it interesting is the way the author tries to make various races interactions or experiences the Dungeon unique. A dungeon gate appears in a fort/village/city, what is the reaction of the locals? Sometimes orderly, sometimes chaotic, and sometimes antagonistic.
The book is told mostly from the first-person perspective of the Dungeon core, who is your typical nerd from our world transported to the fantasy. The way it is told reminds me a lot of the bobverse books. In fact the narrator (Doug Tisdale) for the audiobook sounds a lot like the narrator of the bobverse books. I think if you enjoyed the bobverse books you will like this one. I know I did.
