There is a lot of battle strategy in this book, and the different factions all go through a lot of changes. I liked that not all cats were portrayed as evil; while Felina certainly was, Ace set a good example of how different animals can get along. Even better was his explanation that there is a difference between hunting mice because he is hungry, and hunting them for sport or just to torture them. A lot of the background of the prophecy is explained, as well as Titus' reasons for working with Felina. Pinkie's motivations are discussed, but the most interesting character in the next book with be Pup, who has been badly damaged by all of the various set backs he has had in his life. Brooklyn also plays a large role in this book, and the descriptions of that area are interesting.
