Batman and The Outsiders Vol. 1: Lesser Gods
Several years ago, Batman put the Barrera family of Gotham City into hiding after rescuing them from an organization called the Ark. Now all but one of them has turned up dead... and Batman needs to locate Sofia Barrera before the wrong people get their hands on her-and her surprising power! And when Black Lightning, Katana, the Signal, and Orphan find out what Batman is really up to, their true loyalties will be called into question.
