When Zachary Rawlins stumbles across a strange book hidden in his university library it leads him on a quest unlike any other. Its pages entrance him with their tales of lovelorn prisoners, lost cities and nameless acolytes, but they also contain something impossible: a recollection from his own childhood.

Determined to solve the puzzle of the book, Zachary follows the clues he finds on the cover - a bee, a key and a sword. They guide him to a masquerade ball, to a dangerous secret club, and finally through a magical doorway created by the fierce and mysterious Mirabel. This door leads to a subterranean labyrinth filled with stories, hidden far beneath the surface of the earth.

When the labyrinth is threatened, Zachary must race with Mirabel, and Dorian, a handsome barefoot man with shifting alliances, through its twisting tunnels and crowded ballrooms, searching for the end of his story.
