While the human Ryan has made an enemy of the greatest Angel in Heaven--Anifiel, the Commander of Heaven's Army--Ryan has somehow managed to befriend Anifiel's kind and gentle battle companion, Vithius. Ryan adores the handsome Angel and is all too happy to teach Vithius the ways that humans make love. But how much knowledge is too much? Is he corrupting Vithius as Anifiel has accused? Meanwhile, Demons are beating at the gates of Heaven with renewed aggression. Vithius believes he knows why the Demons are so determined, but Anifiel and Ryan refuse to listen to his theory, afraid to believe what it signifies about their relationship to each other. Can Vithius bring the three of them together? Or will the desire that they continue to resist bring down the entirety of Heaven?
