Kit Thompson, empath and Bow Street Preternatural Division constable, is looking forward to Midwinter. His lover Harry, Viscount Sommersby, is visiting, and Kit has plans to show Harry his London ... and plans for Harry in his bedroom. But Kit’s Chief Magistrate needs him. And the case is important. Personal. Taking up Kit’s time. Even worse, Harry wants to help. And Kit could use Harry’s magical talents. But that means endangering Harry ... something Kit’s sworn never to do.

The Honorable Edmund Rookwood needs to get married. By Midwinter. Or his father will disinherit him. Edmund has always tried to be a loyal son and dutiful heir—unlike his scandalous younger brother. But his father’s ultimatum seems impossible. Edmund has never fallen in love easily, and—according to his father—he’s a disappointment, inadequate, never good enough. Who would ever say yes to him? Sebastian Melior, the Duke of Morinbrough, mathematician and inventor and Edmund’s best friend, offers to help. After all, Sebastian’s also unmarried, and they’ve known each other for years. So Sebastian’s proposal is a logical solution ... But this Midwinter marriage of convenience stirs up unexpected emotions. And Edmund and Sebastian just might discover they’ve been each other’s answers all along.
