Darknet Markets takes a look at the shady side of the internet. Chapter one talks about the various products and services that can be bought on the dark web from chemical weapons to human organs. Chapter two is the most interesting chapter of the book, featuring 4 dark web marketplace. For each of the market places they include information on what they commonly sell and who runs the site.
The Tabletop Gaming Club loved this book. Our favorite part was the write up on Sasquatch's Sporting Goods which we incorporated into our weekly VTM game. We strongly recommend this product to storytellers just for the write up of the four darkmarket places.
PS: We really the author follows this up with a book that expands on the Dark Markets and provides more of them.
