When I got the shipping notification for this book, I wanted to run home right that minute and start reading it. Although this book is very Vimes-and-family-centric, and doesn't involve much of the rest of the Watch, there are a fun and varied cast of characters and an interesting plot that kept me on the edge of my seat the whole time. Young Sam's developing personality is awesome, and Vimes himself never misses a trick. It was great.
