A professional spy for a mysterious Library which harvests fiction from different realities, Irene faces a series of assassination attempts that threaten to destroy her and everything she has worked for.
Irene is teaching her new assistant the fundamentals of a Librarian's job, and finding that training a young Fae is more difficult than she expected. But when they're the targets of kidnapping and assassination attempts, she decides that learning by doing is the only option they have left ...
In order to protect themselves, Irene and her friends must do what they do best: search for information to defeat the overwhelming threat they face and identify their unseen enemy. To do that, Irene will have to delve deeper into her own history than she ever has before, face an ancient foe, and uncover secrets that will change her life and the course of the Library forever.
In Cogman's thrilling seventh Invisible Library fantasy (after The Secret Chapter), Irene Winters, a time-traveling and alternate world jumping librarian, discovers the only thing worse than people trying to kill her is when the people trying to kill her should already be dead. Irene has grown accustomed to disaster striking while she's in the process of buying (or more illicitly acquiring) rare books for the library, but she's unprepared to face off against Lord Guantes, who she distinctly remembers killing, and Alberich, a traitor to the library who's been presumed dead. Somehow they're both back and gunning for Irene and her lover, Kai, a dragon, and her surly new fae apprentice, Catherine. Worse still and certainly more insulting is that they seem to be treating vengeance against her as merely a fringe benefit of a larger and more sinister plot. Without sacrificing the adventure that is a hallmark of the series, Cogman pulls Irene through a multilevel maze of doubts and paranoia that will have readers jumping at shadows, too. Fans will be delighted to find this series still going strong.
