This book has been made to the highest quality; each puzzle is well thought out, presented clearly and each will be a lot of fun to run. I've already included two in a mini campaign of mine, both of which were received with great enthusiasm and enjoyment! This is a great supplement for D&D 5e, and I highly recommend this book to all. I can't wait to run the other puzzles, and I will be getting the other two books in the series. Thank you!
