Catwoman, Poison Ivy and Harley Quinn are tired of playing by other people's rules, regardless of which side of the law they're on. These tough ladies have a new agenda that's all their own and they'll use any means necessary to pursue it. With the Bat away, these sirens will play, and no one—not Hush, the Riddler or the Joker—knows what to expect from the bad girls of Gotham City. Only, sometimes friends can be more trouble than they're worth. Especially when they're unaccustomed to things like loyalty...or sanity.

Catwoman, Poison Ivy and Harley Quinn—they're beautiful, they're deadly, and for the first time in their lives, all three are trying to fly the straight and narrow. Can they trade their lives as supervillains for a life as (relatively) normal roommates? Easier said than done. Especially when maniacs are killing innocents and making it look like the Sirens are the culprits, when Ivy's new civillian identity proves murderously difficult to maintain, and when Catwoman's sister comes to town to rider her of the demon she believes possesses her...and ride her of her life in the process. Collects GOTHAM CITY SIRENS issues #8-14.
