The sixth instalment of this fantastical adventure series. A deal with a Fae leads Irene and Kai to an art heist in Vienna, with a ramshackle team of dragons and Fae - all for the sake of a rare book and its hidden history.

For a Librarian spy,
books are a dangerous business

As Irene tries to manage a fraught Fae-dragon truce and her overbearing parents, she's given a hot new mission. The world where she grew up is in danger and only one book can save it.

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. And some will kill to protect this painting, which hides an extraordinary secret from a past age.
