The Invisible Library

by Genevieve Cogman

Published 15 December 2014

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.

The Masked City

by Genevieve Cogman

The second title in Genevieve Cogman's The Invisible Library series, The Masked City is a wonderful read for all those who enjoyed Mr Penumbra's 24-Hour Bookstore by Robin Sloan, Jasper Fforde's The Eyre Affair or Ben Aaronovitch's Rivers of London.

Librarian-spy Irene is working undercover in an alternative London when her assistant Kai goes missing. She discovers he's been kidnapped by the fae faction and the repercussions could be fatal. Not just for Kai, but for whole worlds.

Kai's dragon heritage means he has powerful allies, but also powerful enemies in the form of the fae. With this act of aggression, the fae are determined to trigger a war between their people – and the forces of order and chaos themselves.

Irene's mission to save Kai and avert Armageddon will take her to a dark, alternate Venice where it's always Carnival. Here Irene will be forced to blackmail, fast talk, and fight. Or face death.

The Masked City contains bonus extra content – secrets from the Library!

When it's your job to save the day – where do you start?

Librarian spy Irene has standards to maintain, especially while on probation. And absconding from a mission via a besieged building doesn't look good. But when her escape route home goes up in flames, what's a spy to do?

Even worse, it seems Gates back to the Library are malfunctioning across dozens of worlds and Irene's nemesis Alberich is responsible – with plans to annihilate the Library itself.

Irene and assistant Kai are posted to St Petersburg, to help combat this threat. Here Alberich emerges, as Irene tries to save her friend Vale and foil assassination attempts. Then one incredibly dangerous opportunity to save the Library emerges. Saving herself would be a bonus . . .

A covert mission.
A royal demand.
And a race against time.


In a 1920s-esque America, Prohibition is in force, fedoras, flapper dresses and tommy guns are in fashion, and intrigue is afoot. Intrepid Librarians Irene and Kai find themselves caught in the middle of a dragon vs dragon contest. It seems a young librarian has become tangled in this conflict, and if they can't extricate him there could be serious political repercussions for the mysterious Library. And, as the balance of power across mighty factions hangs in the balance, this could even trigger war.

Irene and Kai find themselves trapped in a race against time (and dragons) to procure a rare book. They'll face gangsters, blackmail and fiendish security systems. And if this doesn't end well, it could have dire consequences for Irene's job. And, incidentally, for her life . . .

'Captivating story with animated characters . . . cracking pace' - Guardian


A corrupt countess. A spy in danger. And an assassin at large.

Peace talks are always tricky . . . especially when a key diplomat gets stabbed. This murder rudely interrupts a top-secret summit between the warring dragons and Fae, so Librarian-spy Irene is summoned to investigate. In a version of 1890s Paris, Irene and her detective friend Vale must track down the killer – before either the peace negotiations or the city go up in flames.

Accusations fly thick and fast. Irene soon finds herself in the seedy depths of the Parisian underworld on the trail of a notoriously warlike Fae, the Blood Countess. However, the evidence against the Countess is circumstantial. Could the assassin – or assassins – be closer than anyone suspects?

The Mortal Word is perfect for fans of Doctor Who and Sherlock Holmes. Continue the bookish magic with The Secret Chapter. Genevieve is also the author of the Sunday Times bestselling Scarlet - which reimagines the tale of the Scarlet Pimpernel, but with vampires, mages and magic. . .

This is held by Mr Nemo, secretive Fae villain and antique dealer, so Irene and Kai travel to his Caribbean retreat to strike a deal. But in return for the book, they must steal a painting from twenty-first-century Vienna. They’ll join a team of dragons, Fae gamblers and thieves, so their greatest challenge may be one another.
