Theodosia Balfour is in a panic--she has no clue how to handle her new life as a fairy's familiar. She just can't seem to find her place in Cecily's land of decadence, doublespeak, and whimsy.

Moreover, Theo can't stop thinking about Kasra, Cecily's last familiar who is now living a cozy human life without any memories of his time in a fairy's service. All she wants is to tell Kaz how she feels about him, but that's impossible now. Then suddenly, the regent of the fairy kingdom reveals a secret that shocks Theo to her core and thrusts her into the role of detective to solve a thousand-year-old royal assassination attempt.

With time running out to catch the would-be assassin, Theo can rely on only her own wits and unique charm to discover what's really going on.
