This is a compendium book to Perilous Wilds. It is 6 different RPG writers using the rules from Perilous Wilds to create dungeons. It's got some good dungeons in it, but I recommend getting Perilous Wilds also. That has a whole section on how to create dungeons for Dungeon World and even has a lot of tables for random on the fly dungeon creation if you don't want to plan one ahead of time.
I haven't read them closely so I can't say the quality of the dungeons. They look alright from skimming through, but based on the first sentence of the description I assumed there would be dungeon-building advice. Nope, it's six dungeons.
