Angels' Blood is a vampire hunter story with an interesting twist. In this alternate universe angels are at the top of the food chain, archangels are the oldest and most powerful angels, and angels create vampires from willing humans. Both angels and vampires are immortal. Special humans called vampire hunters help angels capture vampires that have broken their agreements or gone rogue.
Archangel Raphael is in charge of New York and he's hired the vampire hunter Elena Deveraux. But she's not going to be hunting a vampire this time. To make it even more interesting Elena is attracted to Raphael and that is all kinds of trouble. I like this story, but Singh seems to be obsessed with sex, much like Laurell K. Hamilton. I prefer vampire hunters who kill vampires rather than lust after them. Still recommended.
