What to expect

Return to the Invisible Library for Irene's most perilous mission yet! The Untold Story is the climactic eighth book in Genevieve Cogman's exhilarating series.

For librarian-spy Irene, this could be her last mission. She has been sent on a terrifying, dangerous task – one which must be kept secret at all costs. To eliminate Alberich.

But even more troubling news emerges. Entire worlds are disappearing, and the Library itself may have something to do with it.

To uncover the truth of these vanishing worlds, Irene and her friends must descend into the unplumbed depths of the Library. What they find will change everything . . .

The Untold Story is the unputdownable eighth book in the Invisible Library series of fantasy novels by Genevieve Cogman.

Genevieve is also the author of Scarlet, a Sunday Times bestselling novel. Set during the French revolution, it is a spellbinding tale of magic, vampires and chaos, written with her trademark wit and pace.

Praise for the series:

'I absolutely loved this' – N. K. Jemisin, author of The Fifth Season

'Irene is a great heroine: fiery, resourceful and no one's fool' – The Guardian

'Cogman keeps upping the ante on this delightful series!' – Charles Stross, author of the Merchant Princes series

Critics Review

I absolutely loved this . . . flavoured with truly unique mythology and a dash of the eldritch. Such clever, creepy, elaborate world-building and snarky, sexy-smart characters!
N. K. Jemisin on The Invisible Library
Irene is a great heroine: fiery, resourceful and no one’s fool, she has a wonderfully droll sense of humour – much like the novel itself
Guardian on The Masked City
Brilliant and so much fun. Skullduggery, Librarians and dragons – Cogman keeps upping the ante on this delightful series!
Charles Stross on The Burning Page
A fantastic addition to Genevieve Cogman’s oeuvre, and paves the way for a deeper exploration of the fantastic world that she has created.
Fantasy Book Review on The Lost Plot
Cogman fills a captivating story with animated characters and propels the narrative at a cracking pace, planting perfectly timed plot twists and reversals of fortune along the way
Guardian on The Mortal Word
Simply a joy to read - deeply atmospheric where it should be, properly exciting when anything’s going on as it generally is, and tender too. This is a series that shows absolutely no sign of losing pace, and I'm already impatient for the next
Blue Book Balloon on The Secret Chapter
Without sacrificing the adventure that is a hallmark of the series, Cogman pulls Irene through a multi-level maze of doubts and paranoia that will have readers jumping at shadows, too. Fans will be delighted to find this series still going strong
