"Never judge a book by its cover. ... Due to her involvement in an unfortunate set of mishaps between the dragons and the Fae, Librarian spy Irene is stuck on probation, doing what should be simple fetch-and-retrieve projects for the mysterious Library. But trouble has a tendency of finding both Irene and her apprentice, Kai--a dragon prince--and, before they know it, they are entangled in more danger than they can handle. ... Irene's longtime nemesis, Alberich, has once again been making waves across multiple worlds, and this time, his goals are much larger than obtaining a single book or wreaking vengeance upon a single Librarian. He aims to destroy the entire Library--and to make sure Irene goes down with it. With so much at stake, Irene will need every tool at her disposal to stay alive. But even as she draws her allies close around her, the greatest danger might be lurking somewhere close--from someone she never expected to betray her. . ."--
