Joker: One Operation Joker (Joker: One Operation Joker #1)

The Joker like you’ve never seen him before... as a single father?! After a fateful encounter with Batman that results in the Dark Knight de-aging to a baby, Joker takes it upon himself to raise the child into the crusader of justice! But does the Clown Prince of Crime really understand what it means to be Batman - or, more importantly, what it means to raise a baby all by yourself? Everyone needs a babysitter who makes them laugh, right?
