This book is fantastic! The team put in a lot of work to deliver these super fun adventures. The artwork is amazing. My group had a lot of fun with the one we played and I'm looking forward to running the rest of the book! I think anybody playing D&D will love this. I think these sessions can be great to get someone new into the game too. They do a great job of getting all the elements of D&D into a session that you can play in under a couple of hours. Just make sure they know that the whole dying/TPK part is outside the norm. Buy this book! Your poor player characters might regret it but you won't!
The sheer number of one-shot adventures you get out of this module makes it more than worth it. I don't know of any other source where you can get 15 adventures of this quality for the price. The value of this book is truly unbeatable. You know what else are unbeatable? The adventures a party of unfortunate heroes will face in the book!
Also, a very specific thing that endeared me to this book. I have dreamed of a statblock for The Lord of Blades. This book has one, and it is absolutely terrific.
