Irene is a professional spy for the mysterious Library, whose staff are sent to different realities to harvest dangerous and mystical fiction.

Irene has been posted to an alternative steampunk London along with her enigmatic new assistant, Kai. Their mission: to retrieve a dangerous edition of Grimms' Fairy Tales. But it has already been stolen.

In London's underground, the laws of nature have been bent – supernatural creatures and unpredictable magic stalk the land. The city is home to vampires, werewolves – factions that are all prepared to fight to the death for this book.

Irene must face a web of deadly danger, deception and secret societies. Her new assistant is hiding secrets of his own. Yet failure is not an option – the nature of reality itself is at stake . . .

Continue the journey with the adventurous second title in the Invisible Library series, The Masked City.

From now on, let it be known, that I am no longer searching for Narnia when I open doors. I am searching for the Library as invented by Genevieve Cogman in The Invisible Library series. This magic library exists between worlds and between times and contains more books than the most accomplished bookworm or book dragon could hope to acquire.

The Invisible Library, book one in this debut series by Genevieve Cogman, is a setup book. The narrative is a bit heavy and there were points where I felt the action was dragging and other points I was a bit overwhelmed. But this is the first novel in a series and the world is complicated. It takes a bit to get settled in and get used to the rules. Cogman reveals many details about the universe, inside and outside of the Library including the Library’s own special magic that requires mastery of The Language. I was fascinated by the secrets of the library (apparently you don’t age when you are in the Library), however, there are hints throughout the novel that perhaps the Library isn’t all it’s cracked up to be.

There’s a little bit of everything in The Invisible Library—mystery, magic, fae, vampires, werewolves, books and of course, DRAGONS. I am intrigued enough with the world of The Invisible Library to give book two, The Masked City, which releases soon a chance. I can’t seem to resist decent books about libraries, fellow bookworms and dragons.
