Gotham City Sirens #1

In "Frauengespräche," Harley Quinn and Poison Ivy share a tense, revealing conversation that veers between camaraderie and suspicion, while Selina Kyle uses a method taught by Talia al Ghul to keep Batman’s identity hidden—though not from the women themselves. When Harley intervenes to rescue Bruce Wayne from kidnappers, she unwittingly saves Thomas Elliot, setting off a chain of events that tests loyalty, deception, and the fragile bonds between women who walk the line between ally and enemy.

In "null," Poison Ivy and Harley Quinn find themselves caught in a deadly game orchestrated by Hush and Gaggy, who've assumed the identities of Bruce Wayne and the Joker. With the city's shadows closing in, the two women must rely on each other's strength and cunning to survive a trap that blurs the line between ally and enemy.
