The Secret Chapter

Librarian spy Irene needs a specific book to prevent her home world from sliding into chaos, and the only copy resides with a mysterious Fae information broker named Mr. Nemo. To obtain it, she must join a crew of unlikely specialists, including a dragon techie, a Fae thief, a gambler, a driver, and hired muscle, for a heist targeting the Kunsthistorisches Museum in Vienna. Genevieve Cogman's sixth Invisible Library novel leans into the Ocean's Eleven structure with evident delight, leaning on the frictions between characters who have excellent reasons not to trust each other.

Kristin Atherton has been the voice of this series throughout, and her performance gives Irene the precise combination of competence and dry wit the character requires. She handles the ensemble cast with clarity, distinguishing each member of the heist crew without turning them into sketches, and her pacing through the museum sequence gives the novel's climax the playful tension it is designed for.
