I have recently purchased this book in the English version, as a way to learn more about being a human Pup, and more about Puppy-play. The author really describes what Puppy-play is, and also breaks down the hierarchy of pups, and roles they play in a pack. The book is very informative, interesting, well written, and also has color photos well. I'm really pleased, and very happy to have a book that goes into detail of what it is to be a Pup, the roles that are associated. It also goes into a bit about the community, and the diversity of the kink/fetish community in a positive and proud light. It is a very valuable book that if you're just starting out, or have been in the scene for a while, should have a space for this book in their library. This book is one that I am happy to have in mine, and have learned so much since started reading. I highly recommend picking up a copy; and can guarantee your thirst for knowledge on this subject will be quenched.
