A new energy drink has become all the rage in Gotham, thanks to a rather unorthodox marketing campaign! Caffeinated citizens are being pushed to riot for the chance to participate in "hunting" parties that involve herds of bio-mechanical beasts flooding the streets, putting civilians and the environment at risk. Thankfully, Catwoman, Harley Quinn, and Poison Ivy are on the case! Together again as the Gotham City Sirens, they're here to prove that sometimes the only way to stop bad is with even worse!
Join the rising-star team of Leah Williams and Matteo Lolli as they take the Sirens on a wild romp through their city, facing down everything from cowboy creeps to salacious internet streamers in the complete series, Gotham City Sirens #1-4!
