I took my time to read through it and run some of the puzzles before writing a review. I can now with with absolute certainty recommend this to anyone who wants more Puzzles in there D&D, but either sucks at making them or does not have the time. The way the book is set up it is super easy to see how hard the puzzle will be and what hints you can hand out.
Top it off with several really neat Appendix that either give you weird Dungeon rooms to plop into your game, a few magic items or a really helpfull guide on how to come up with your whole puzzle you can't really go wrong for the amount of money.
