It's Franklin's birthday! While his surprise birthday party is being set up, Luna takes Franklin book shopping. They find a padlocked book of fairy tales, which the bookseller tells them is full of dangerous magic. Luna's tortoise, Neil, can't help picking the lock… but when he peers inside, the book swallows him whole. Franklin and Luna dive into the book to rescue Neil. They tumble into cobwebbed forests and meet dusty fairy-tale characters who have been trapped inside the pages for hundreds of years…

This follow-on from the highly sucessful Franklin's Flying Bookshop and Franklin and Luna go to the Moon offers a witty and vivid reimagining of well-loved fairy tale characters, bringing the magic of classic fairy tales into the 21st century through exquisite illustrations and a rhythmic, literary text.
