Born in Gotham's crime-filled nights, on a mission of vengeance, and determined to reclaim his once-great city from those who stole its innocence, his name is Man-Bat and he's on a holy mission to destroy Batman forever.

Allied with the mysterious new Shush, Man-Bat will stop at nothing to unleash his Cult of the Bat and its thousands of poisoned bats on Gotham. Batman and Robin have enough on their plate when Flatline, Damian's crush from the Lazarus Tournament, shows up with her own mysterious plans. Can the three unlikely allies stop Man-Bat and Shush in time? And what does Gotham City High School have to do with it?

Joshua Williamson (The Flash), Simone Di Meo (Batman: White Knight Presents: Red Hood), and Nikola Čizmesija (Sword of Azrael) continue the tale of Bruce and Damian Wayne rebuilding their life together as father and son while fighting crime as Batman and Robin. Collects Batman & Robin #7-13!
