The Invisible Library

One spy. One dangerous book. One deadly mission. The first in a delightful fantasy mystery series, The Invisible Library is the astounding debut from Genevieve Cogman.

Irene must be at the top of her game or she'll be off the case – permanently . . .

Irene is a professional spy for the mysterious Library, which harvests fiction from different realities. Along with her new assistant Kai, she's posted to an alternative London. Their mission – to retrieve a dangerous book. But lo and behold, when they arrive, it's already been stolen. London's underground factions seem prepared to fight to the very death to find her book.

In this world teeming with supernatural creatures and unpredictable magic, Irene soon finds herself up to her eyebrows in a heady mix of danger, clues and secret societies. And Kai is also hiding secrets of his own. Yet failure is not an option – the nature of reality itself is at stake.
