About this Collection
This collection kicks off the 2009 Gotham City Sirens series, bringing together Catwoman, Harley Quinn, and Poison Ivy as an unlikely trio navigating the criminal underworld of Gotham. Written by Paul Dini with art by Guillem March, the volume follows the Sirens as they form a fragile alliance while dealing with threats from the Joker, the Riddler, and their own tangled histories. It collects issues #1-13 of the monthly series.
"Union" kicks off Gotham City Sirens #1 with a tense trio of women navigating the city’s shadows—Selina, Harley, and Ivy—while a secret identity hangs in the balance. Written by Paul Dini and brought to life by Guillem March’s sharp art and José Villarrubia’s vivid colors, the issue sets a moody, suspenseful tone as Selina employs a tactic taught by Talia to shield Batman’s true identity from her allies. When Harley rescues Bruce Wayne from kidnappers, she doesn’t realize the man she’s saving is actually Thomas Elliot—setting the stage for a web of deception and danger. Cover by Guillem March.
