The Burning Page (An Invisible Library Novel)

Librarian spy Irene and her apprentice Kai return for another tremendously fun, rip-roaring adventure, (A Fantastical Librarian) third in the bibliophilic fantasy series from the author of The Masked City.

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 to find 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 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 from somewhere close someone she never expected to betray her..."
