Billy Batson's never been a team player, and becoming the superhero Shazam didn't seem to change that much. But his new strength and stamina will make football a breeze—which is good, because his school needs a new quarterback! Between football practice and superhero training, Billy's muscles are getting bigger, but so is his ego.

Who's a good boy? Jester is. Well, he wants to be. Maybe he is? He's The Joker's dog, so of course he's funny, but his sense of humor is about to be put to the test. Because when the super-villains of Gotham get thrown into Arkham, their henchpets go to the maximum-security pound known as Barkham Asylum. Being the Clown Prince of Crime's dog doesn't win Jester any friends behind bars, especially after he gets a tough-talking stray cat named Penny tossed into lockup with him.
