Within the walls of a centuries-old building lies the magical Library of Illumination, a place where books literally come to life. 17-year-old Johanna Charette is the youngest curator ever chosen to oversee the day-to-day operation of the library and she knows, in case of trouble, having an assistant can be invaluable, so she hires 16-year-old Jackson Roth to give her a hand. Jackson gets off to a rocky start, but manages to prove his mettle. Besides, he's kind of cute and a lot of fun. Johanna is charming and brilliant-and a natural born leader. She keeps the library operating on an even keel. Jackson is clever and intrepid. He relies on his wits to keep them out of danger when trouble arises. Unfortunately, his derring-do is one of the reasons why they sometimes find themselves in awkward situations. So it shouldn't be any surprise when his wanton curiosity sparks a journey to a distant realm, where they end up with front row seats in a battle against an ancient foe.
