In this book, it describes the Clans and all the important cats of the Warriorcats series by Erin Hunter. It describes each cat and what they did in the books. It also talks about the clans and what they represent, the cats before the clans. It's very interesting to learn about each cat's history.
I'd recommend this book to any cat lover, action lover, and, of course, anyone who reads the Warriors series. I rate it 8.5 out of 10 because it shows some cats on the front that aren't in the book. And, though it shows so many of the cats, they really should have included more about the Clans themselves and other history.
