Summary:
Owen and Bethany have sworn off jumping into books for good. But they didn't make any promises about not jumping through strange portals that lead to a comic book world. Jupiter City was once filled with brightly costumed superheroes and villains, but nowadays, there's nothing left but the Dark. Even the villains are terrified of the Dark's shadows, and most of the heroes have either disappeared or been lost to mind control. The one hero who might have stopped all of this, Doc Twilight, has been imprisoned by the Dark.
