Matthew Trahan is a two-thousand-year-old guardian angel. He's part angel and part, well, devil, as you would call it. He's the product of a liaison between Lucifer and guardian angel Adela. Matthew is a very powerful creature. But when he meets Collin, his human mate, he notices that no power in the world can make Collin love him.
Collin is very reluctant and want's nothing to do with Matthew. He doesn't know it yet, but soon, he will be in for the fight of his life and that of his friends as well. Collin will encounter hell hounds and other stuff the belong in nightmares. Friends go missing, and enemies keep popping up at what seems on every corner of the street. Then there's Allan, Collin's abusive ex-boyfriend. Also, there's more to Collin than meets the eye, stunning even Matthew and the rest of the guardian angels. Hell, it even stuns Lucifer.
