Physicist Portia Harding's life is grounded in facts. There's nothing that can't be explained by logic and science. Until she travels with her best friend to England—and accidentally summons an ethereal Virtue who bequeaths her gift of weather control to Portia . . . Now Portia's walking around with a literal cloud over her head—and a heart-stoppingly handsome maniac trying to kidnap her. But Theondre North is no run-of-the-mill maniac. He's a nephilim—the son of a fallen angel—who needs Portia's help to change his fate. Problem is, Portia's down-to-earth attitude frustrates beings from both heavenly and hellish realms—and gets Theo turned into a vampire. But at least he has Portia to satisfy his newfound hungers—and possibly save his soul.
