Initially I received the PDF of this as part of being a Patreon subscriber to Ponyfinder and I liked it so much that as soon as it became available as a print on demand book as well I made sure to buy a copy for myslef. For me the updeate to Hybrid Blood to Pathfinder Second edition was the main selling point but the new races in here are great as well. The book provides a great way of building and running anthropomorphic animal races which in some cases does mean furries. Personally I am using this as part of my own homebrew world to define the kinds of an ancestries I am offerening to players as a replacement for humanity. As far as third party support for what I consider the best version of D&D I have planned this book is a must have.
