A brilliant con artist and a secretive librarian collide in New York Times bestselling author Kalyn Josephson’s enchanting adult fantasy debut packed with twists, tricks, slowburn romantic tension, and magical creatures -- perfect for fans of S.A. MacLean, Mai Corland, and K.A. Linde.

Former con artist Kasira expected to spend her life as a soldier, miserably working off her prison sentence by hunting down magical creatures for the fanatical kingdom of Kalthos. But when the Kalish ambassador arrives with a non-negotiable assignment, Kasira finds herself swept into the biggest con of her life: infiltrating the Library of Amorlin. 

As the heart of all magic and the protector of magical creatures throughout the six kingdoms, the Library is historically politically neutral. Kasira is meant to pose as the new Assistant to spy for the ambassador and destabilize the Library from the inside, clearing the way to dethrone its Librarian. 

But when she arrives, Kasira learns that the Library is not all she was told it would be. Neither is the prickly, handsome Librarian, Allaster, whose own monstrous secrets are about to catch up with him. 

Swept into the enchanting world of the Library, Kasira’s reluctant con is jeopardized by her growing affection for the wondrous life the Library promises…and by her complicated, burgeoning attraction to Allaster. As the ambassador’s game closes in, Kasira must decide where her loyalties lie: to her newfound home, or to her own survival?
