Uncanny Treks: Gotham City Sirens- Division (2012, Comic)

The Sirens' last stand. Bob and Matt close out Paul Dini's Gotham City Sirens with Division (vol. 4), collecting the final issues (#20-21, 23-26). Harley breaks into Arkham to kill the Joker — and releases him instead, sparking a Joker-Harley takeover that takes Batman and Catwoman to put down. Then Ivy springs Harley, and the two turn on Catwoman — until Selina reveals she's been using her Batman connections to protect them all along. The series ends with the three going their separate ways. Matt's not ready to say goodbye; Bob calls it the right ending at the right time.
