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

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. With her detective friend Vale, she must track down the killer – as peace hangs by a thread.

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 only circumstantial. Could the assassin – or assassins – be closer than anyone suspects?
