Quiet and predictable-that's how Jonah Reed likes his life. A small-town librarian with a passion for ancient maps and forgotten tales, Jonah has always been content to live vicariously through the stories he reads. But when a mysterious package arrives at the library containing a centuries-old map and a cryptic note, his carefully ordered world is turned upside down.

Against his better judgment, Jonah follows the map's trail, finding himself swept into a whirlwind of danger and discovery. Teaming up with Zara Quinn, a fiery treasure hunter with a knack for breaking rules, and Tobias Harker, a brooding historian with secrets of his own, Jonah embarks on a journey across deserts, jungles, and treacherous seas.
