For centuries Mira has been a nightwalker -- an unstoppable enforcer for a mysterious organization that manipulates earth-shaking events from the darkest shadows. But elemental mastery over fire sets her apart from others of her night-prowling breed...and may be all that prevents her doom.
The foe she now faces is human: the vampire hunter called Danaus, who has already destroyed so many undead. For Mira, the time has come to hunt or be hunted.
But in a dimension just beyond the worlds boundaries, a banished race stirs dangerously, hungry for power, for domination, for vengeance. Already a protective seal has been breached: already blood flows like a river through the world's great cities.
And only the collaboration of two sworn enemies can save humankind...and its ferel brethern.
