For each Alvian there is one perfect Resonance Mate. When Davin—an alien unlike any other—finds Callie O'Hara, he finds hope as well. But she's human. Can she forgive his race for what they've done to humanity and the Earth?

Rick is a human survivor of the alien invasion. He doesn't believe in much, but when he sees Callie, he begins to believe in love at first sight.

Davin defies his own government to be with Callie, but he cannot keep her all to himself, for she has another true mate in Rick. Can the three of them come to terms with the unlikely relationship? And can they survive when the Alvian government sends assassins to their door?
