Kasira used to be a masterful con artist: choosing her target, building trust, judging the precise moment to make her move. Now, she's keeping her head down and working off a lengthy prison sentence. But Kasira's past catches up to her when she's offered a deal: her freedom in exchange for one last con-infiltrate the fabled Library of Amorlin.

When Kasira goes undercover as the new Assistant Librarian, she enters an enchanting world brimming with books and magical creatures, tempting her with a life she can never have. But Kasira's real future depends on her charge: the long con to bring down the Librarian. Unfortunately, Allaster is as prickly as he is handsome … and hiding a beastly transformation that could destroy him.

Kasira has to decide: take down Allaster and destroy the only place that has ever felt like home-or be herself for once in her life, and risk losing it all anyway.

"A stunning, absorbing, and timely tale about a wondrous library, magical beasts, and a conwoman with both everything and nothing to lose."-Sarah Beth Durst
