Sophronia’s first year at Mademoiselle Geraldine’s Finishing Academy for Young Ladies of Quality has certainly been rousing. For one thing, finishing school is training her to be a spy.

A conspiracy is afoot—one with dire implications for both supernaturals and humans. Sophronia must rely on her training to discover who is behind the dangerous plot and survive the London Season with a full dance card.
