I listen to a fair number of podcasts by professional game reviewers, and one of their inside jokes and bete-noires is the word "fun". "Fun" is a word that people turn to very naturally, and yet it doesn't convey much information beyond the fact that you liked the thing. E.g. if a game is "fun", that doesn't tell you why the reviewer liked the thing; was it the graphics, the controls, the lore, the story, the core gameplay, the explosions, the upgrades, the community, etc. etc. etc.?
Anyway, this book was really fun. The author consistently sets up interesting, humorous, dangerous, witty, snappy, and simply well-written adventure situations for his band of heroes as they trek across civilization and the Wyld in order to rescue one of their kids from a horde of monsters. It's like having a really great DM and party recount their cleverest and most enjoyable encounters. Much of the Monster Manual makes an appearance in this book, and the author is clearly a huge fan of D&D and its tropes. The five main heroes and their relationships are also fleshed out surprisingly well, e.g. to a degree and with an intelligence way beyond what would be required to just tell an adventure story, but not to the point where it becomes burdensome or the main focus of the novel. If there is one slight criticism I would make of the story is that the author is a little too protective of his characters, and I think the story would be better if they had a little less plot armor. Oh, and there were a few too many pop culture references. Still! If you'd like to read an exciting, funny, and clever fantasy adventure story you can't do better than this. It is very beer and pretzels, but it is the absolute best beer and pretzels.
