My Angel Lover, Have Mercy On Me

For his sins, his angel lover will bring him to justice.In 1665 Scotland, five years after the Black Plague, Jophiel is a former angel who removed his wings in an act of self-punishment for falling in love with a vampire, Frederick. One day, two old friends, Michael and Zad, give him the chance to return home. Their price? Capture his former lover and take his head. Lord Frederik Jasper Grimm is a Belial Vampire, born with half a soul and mortal emotions.
Forced to destroy a village of innocents to save his sister Amelia from a murderous sorcerer, Frederik is on his way to his enemy's keep when Jo appears and captures him. Before Jo can raise his sword and take his head, Frederik begs for mercy and explains why he destroyed the village, counting on Jo's good nature to spare him, but Frederik has lied to Jo before. Still, Jo cannot bring himself to kill Frederik, but he dares not set him free, either.
His only choice is to keep Frederik his prisoner until Michael returns to explain why Jo would be sent to execute a supposedly innocent vampire...and all the while, he must keep his knew mortal state a secret.
