In this thrilling historical fantasy, time-traveling Librarian spy Irene will need to delve deep into a tangled web of loyalty and power to keep her friends safe.
Irene is trying to learn the truth about Alberich-and the possibility that he’s her father. But when the Library orders her to kill him, and then Alberich himself offers to sign a truce, she has to discover why he originally betrayed the Library.
With her allies endangered and her strongest loyalties under threat, she’ll have to trace his past across multiple worlds and into the depths of mythology and folklore, to find the truth at the heart of the Library, and why the Library was first created.
My thoughts: I have thoroughly enjoyed this series and as this is the last book before the author takes a pause to work on another project (which sounds excellent fyi) I relished every page. Irene and her friends are tested to the extreme and in the end she has to confront the secrets hidden at the heart of the library.
When I worked as a librarian our library’s secrets were in the office, which no borrower was permitted into, but I saw them and took the oath, so I can’t tell you what lies at the heart of a library.
The truce agreement between the dragons, fae and Library are stretched thin, the Librarians themselves are under siege and it feels like the end for the book swiping adventures that Irene has been on. Who built the Library and why?
