A Book Come to Life- Adventure Time Fan-Fiction

A book inspired to me by the show Adventure Time. One day when Princess Bubblegum couldn't find a simple enough way to figure out her equation the Ice King kidnapped her. She found a mysterious book and decided to read through it. She experimented with the book and ended up blacking out blacked out. She and her friends go through a crazy adventure looking for ways to reverse the effect (which you will find out soon).
