Hadrian Cross is a half-angel with an attitude. He avoids his goody-two-shoes angelic family and prefers to slum with humans until he tangles with the deadly vampire queen, Esme. Fearing for the lives of his mortal friends, he approaches an ancient archangel for help, but there are strings—lead mortal woman, Grace Black to her soulmate. Hadrian happily complies. All women want to fall in love, right? Book store owner and cheerful snark, Grace Black doesn't believe in soulmates, marriage or regrets so when an angel arrives at her front door espousing the virtues of true love and destiny, she laughs in his face. Then makes him take off his shirt to prove he has wings. Grace doesn't miss the ex who's her supposed destiny, but Hadrian shirtless and in full flight is not something she wants to forget. She agrees to his ridiculous offer mostly out of boredom and curiosity, but as they spend time together, they both worry the universe has its wires crossed.
