Sins of the Heart by Eve Silver
Sins of the Heart (2010) is the first in Eve Silver's new Otherkin trilogy.
Half human, half god, Dagan Krayl is the Underworld's most powerful soul reaper. When one of his brothers is murdered, Dagan must use every ounce of his power to hunt down those responsible for his brutal death. But he must move swiftly—and carefully—if he's to have any chance of resurrecting his brother.
Yet that resurrection could wreak havoc on the mortal world. As an Otherkin, Roxy Tam has sworn to protect the human race, and it's her mission to stop Dagan. But when she sees him face-to-face, she realizes that she has seen him once before—a meeting that changed her life forever.
Neither Dagan nor Roxy expect to join forces for the sake of mankind. Or to have their loyalties tested as they struggle against the potent desire that threatens to consume them both….
Roxy is a strong, self-reliant survivor of the foster care system and now a Daughter of Aset. Since the Daughters of Aset are the sworn enemies of Dagan's father, Sutekh, he actually warned her to stay far away from them when he initially met Roxy eleven years before the main part of the book occurs. After that warning, Roxy found them and became part of the group.
Despite resolving Dagan and Roxy's personal relationship before the end of the the book, the story of what happened to Dagan's brother, Lokan, is left hanging. Just a warning to not read this expecting to find a complete stand-alone book.
Although I very much enjoyed reading about the paranormal world created by Silver and plan to read the next two entries in the series, Sins of the Soul and Sins of the Flesh, the book is a little short on romance for my taste. Actually, Dagan and Roxy spent a great deal of the book apart, and that's not exactly what I'm expecting when reading a romance novel. File this one more under urban fantasy.
My overall personal rating of Sins of the Heart is a B.
