Life is boring when you live in the real world, instead of starring in your own book series. Owen knows that better than anyone, what with the real world's homework and chores. But everything changes the day Owen sees the impossible happen -- his classmate Bethany climb out of a book in the library. It turns out Bethany's half-fictional and has been searching every book she can find for her missing father, a fictional character. Bethany can't let anyone else learn her secret, so Owen makes her a deal: All she has to do is take him into a book in Owen's favorite Kiel Gnomenfoot series, and he'll never say a word. Besides, visiting the book might help Bethany find her father. Or it might just destroy the Kiel Gnomenfoot series, reveal Bethany's secret to the entire world, and force Owen to live out Kiel Gnomenfoot's final (very final) adventure.
Mysteries abound as memory-erased Owen Conners, boy magician Kiel Gnomenfoot, and their half-fictional friend Bethany confront secrets, stolen memories, hidden clues, surprising twists and endings, and some very familiar faces.
Aided by old friends and new, Owen and Bethany try to bring the light back to Jupiter City, a comic book world where they discover a link between the Dark and Bethany's father.
Owen is trapped in a time travel plot-your-own-adventure book, controlled by the reader, and a bizarre fellow prisoner, Kara Dox, might be his only hope for escaping to save Bethany.
After Nobody destroys the connection between fictional and nonfictional worlds, causing nonfictional people to lose their imaginations, Owen and Bethany must risk everything to save multiple realities.
