The third instalment of this sparkling fantasy adventure. Irene the librarian spy faces deadly danger and impossible decisions, as the future of the library rests on her shoulders. Perfect for fans of Jodi Taylor and Jasper Fforde.

The Invisible Library series by Genevieve Cogman is the perfect read for book-lovers everywhere. It's a fast-paced adventure - think Doctor Who, but with Librarian spies. Reviewers have also found a dash of Discworld and Jasper Fforde, a hint of Sherlock Holmes and a great deal of humour.

The first novel in the series, The Invisible Library, introduces Irene and her assistant Kai: a pair of librarian spies on a mission to retrieve a dangerous book from a parallel world. In an alternative version of Victorian London - where magic runs rife - they soon find that the book they seek has already been stolen. Cue a whirlwind quest down a rabbit hole of forbidden societies, twisted plans, new friends, old enemies and the occasional dragon. What could possibly go wrong? Irene and Kai's (mis)adventures continue in The Masked City, which takes them to a sinister version of Venice, and then in The Burning Page and beyond things really start to heat up . . .

'Brilliant and so much fun. Skulduggery, Librarians, and Dragons - Cogman keeps upping the ante on this delightful series!' - Charles Stross

'A breath of fresh air' - Guardian

The Invisible Library series is tailor-made for bibliophiles . . . It's immensely entertaining, and I continue to love Irene and her third person narrative voice: she's practical, analytical, and competent, and she handles the absurd situations in which she constantly finds herself with aplomb
