I'm not quite sure what this book wants to be. It's about 25% Hitchhiker's Guide to the Galaxy, 25% Indiana Jones, and 50% the most boring part of the hike to Mt. Doom from Lord of the Rings. Seriously you won't get this from the marketing but 90% of the book is just Duke and the ninja walking around a bronze age civilization and having long (like...really long) conversations about who should stand where.

Duke LaGrange commits the worst sin a comedy can commit. It's boring. It's not so bad its good. It's just a bland study of a very tropey OC.

Like I can't emphasize enough that Duke LaGrange is your friends D&D character concept that he won't shut up about. He's a loveable idiot, but also sometimes very competent, and you'd better believe he's good at violence.
