Batwoman (Batwoman Vol. 3 #2)

The criminal haven of Coryana has changed completely in the years since Batwoman left! The biggest change of all? Her closest friends are now her enemies-or they’re corpses! It’s time for Kate Kane to cut to the heart of what’s happening here, and find out who brought the deadly bioweapon Monster Venom into Coryana... but she might get her own heart cut out in the process, by the unbeatable assassin known as the Knife!
