Holy shit, the title fits this volume well.

This is a relentless attack on Catwoman and her people. Black Mask hates Catwoman for steeling from him so he teams up with a old childhood friend of Salina and together they take Catwoman down. But not just her, but her entire cast of characters, using them, torturing them, killing them, and leaving Salina to try and fix it all. On top of that get 3 issues after that arc with all the characters trying to pick up the pieces to their lives, and of course it isn't going well.

This is emotional, brutal, and excellent all at once. The art though in the 3 issues at the end is really jarring and way weaker than the previous issues.

Still a 4.5 out of 5, pushing it to a 5 out of 5.
