Batman: Urban Legends, book 3
Vita Ayala, Mark Russell et Collectif2022

Every year Batman and Zatanna are tasked with containing a curse they released upon the world as teenagers. But this year is different. They are emotionally further apart than they have ever been before, which leads the curse to break free. Batman and Zatanna will have to go to the ends of the DCU to repair their relationship and contain the curse. With some help and hinderances from John Constantie...

And in a world outside of magic: Batman has his hands tied—literally—and it's up to the furry tails to keep things under control! Ace the Bat-Hound, the goodest boy in the DCU, embarks on a Batman-less adventure as he assembles a team of unlikely DC Super-Pet friends. When things go awry and Batman's separated from his furry pal, it's up to Ace to find his way back to his partner. But he'll have to navigate through illegal experiments and pet cemeteries first!
