(Book)

Series numeration from Goodreads.com.

"Nothing ever happens in Filomena Jefferson-Cho's sleepy little suburban town of North Pasadena. The sun shines every day, the grass is always a perfect green, and while her progressive school swears there's no such thing as bullying, she still feels bummed out. But one day, when Filomena is walking home on her own, something strange happens. Filomena is being followed by Jack Stalker, one of the heroes in the Never After, a series of books she loves about a brave girl and her ragtag group of friends who save their world from an evil enchantress. She must be dreaming, or still reading a book. But Jack is insistent -- he's real, the stories are real, and Filomena must come with him at once! Soon, Filomena is thrust into the world of evil fairies and beautiful princesses, sorcerers and slayers, where an evil queen drives her ruthless armies to destroy what is left of the fairy tribes. To save herself and the kingdom of Westphalia, Filomena must find the truth behind the fairytales and set the world back to rights before the cycle of sleep and destruction begins once more." -- Adapted from dust jacket.
