The second instalment of this bookish fantasy adventure series. A mystical identity is revealed, and the fates of all dimensions rests on the shoulders of one daring library spy . . .

Irene is ready for action - but so are her adversaries.
Librarian-spy Irene is working undercover in an alternative Victorian London, for her mysterious supervisors. Here it's business as usual - until her assistant Kai is abducted. Kai's part-dragon heritage means he has powerful enemies, and this act of aggression could trigger a war between his people and their greatest rivals. As they each represent the forces of order and chaos themselves, matters could turn unpleasant.

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 she'll face mayhem - at the very least.
