New York Times bestselling author Nalini Singh returns to her world of dark passion and immortal power-and to one of the most seductive and impenetrable heroes ever to stalk the Guild Hunter landscape . . .

Naasir is the most feral of the powerful group of vampires and angels known as the Seven, his loyalty pledged to the Archangel Raphael. When rumors surface of a plot to murder the former Archangel of Persia, now lost in the Sleep of the Ancients, Naasir is dispatched to find him. For only he possesses the tracking skills required-those more common to predatory animals than to man.

Enlisted to accompany Naasir, Andromeda, a young angelic scholar with dangerous secrets, is fascinated by his nature-at once playful and brilliant, sensual and brutal. As they race to find the Sleeping archangel before it's too late, Naasir will force her to question all she knows . . . and tempt her to walk into the magnificent, feral darkness of his world. But first they must survive an enemy vicious enough to shatter the greatest taboo of the angelic race and plunge the world into a screaming nightmare . . .

I don't know how Nalini Singh does it but this series just continues to get better and better with every single book. Out of all of Raphael's Seven Naasir had mostly stayed off my radar until we started to get to know him a little better in Archangel's Shadows but those glimpses had me dying to know more and I incredibly excited to discover that he was going to be the main character in Archangel's Enigma.
