When young Danny Crawford's father and a priest conspire to subject him to conversion therapy, Danny only sees one way out. But little does Danny know he'll soon have a sentinel watching from the darkness, a guardian angel in the most unlikely form imaginable. Damien, a vampire, is inexplicably moved by Danny's plight. He takes it upon himself to make sure Danny's father and the priest can never hurt him again, giving Danny a chance at a normal life. As Danny grows up, Damien struggles to keep the boy—and later the young man—from harm. He does not dare go any further, no matter how much he wants to. To do so would ruin everything he's tried to do for Danny. He doesn't realize that as Danny embarks on a successful modeling career and begins dating, Danny feels empty, longing for something—or someone—just beyond his reach: a shadow, a presence he despairingly believes forever lost to him.  When brutality and violence threaten Danny again, Damien must make a decision—risk revealing himself to Danny, or leave Danny to his fate.
