This is one of the first books that I read from this genre, and now, much later, with experience I can look back on it and say that it hits every beat that defines the dungeon core stories perfectly.
I would go as far as to say that it handles the adventurers / dungeon town better then a good number of other famous books, as it doesn't forget what the story is supposed to be actually about, the dungeon core and its dungeon.
I would recommend this book to any even slightly interested in dungeon core stories, as it should be able to satisfy people who have already read 10s of books in this genre and beginners who are just testing the waters.
