Harley Quinn & The Gotham City Sirens (Omnibus)
Catwoman, Poison Ivy, and Harley Quinn are tired of playing by other people's rules. These tough ladies have a new agenda that's all their own, and they'll use any means necessary to pursue it. But can they get along and work as a team?
This omnibus collects the complete 26-issue series as well as Catwoman #83, with an introduction by Paul Dini!
