Life flourishes in the Book, a world of stacked realms spanning the ages, like the pages of an epic chronicle. Each page opens to domains evoking the glory of ancient empires, the passion of the Renaissance, or the adventure of court intrigue. Those who can travel between them are page turners, blessed with the power to go from one page to the next.

For investigator Fiona Thorne, turning the page is normal life. Solving mysteries is where the excitement lives. No case is too small to ignite her curiosity, no page too familiar to explore. She is determined to leave her mark in the Book, no matter where her cases may lead.
