It is 1984 and forty years since Simon, Patricia and Evelyn and Larry first stepped through a magical library door into the enchanted world of Folio. When Patricia's daughter, Jewel, makes a mysterious discovery in an old bookshop, she begins a quest that will make her question everything she thought she knew.
Summoned to Folio, she must rescue a missing prince, helped only by her pet hamster and a malfunctioning robot. Their mission to the Frozen Sea will bring them face-to-face with a danger both more deadly and more magnificent than they ever imagined.
