After almost twenty years, Emery Hazard finally has the man he loves. But things with his boyfriend and fellow detective, John-Henry Somerset, are never easy, and they've been more complicated lately for two reasons: Somers's ex-wife and daughter. No matter what Hazard does, he can't seem to get away from the most important women in his boyfriend's life.

While Hazard struggles with his new reality (changing dirty diapers, just to start), a bizarre murder offers a distraction. John Oscar Walden, the leader of a local cult, is found dead by the police, and the case falls to Hazard and Somers. The investigation takes the two detectives into the cult's twisted relationships and the unswerving demands of power and faith.

But the deeper Hazard looks into the cult, the deeper he must look into his own past, where belief and reason have already clashed once. And as Hazard struggles to protect the most vulnerable of Walden's victims, he uncovers a deeper, more vicious plot behind Walden's murder, and Hazard finds himself doing what he never expected: racing to save the killer.

Only, that is, if Somers doesn't need him to babysit.
