Nightwalker

All her life, Takala Rainwater hoped to find the mother who'd abandoned her and her sisters. But, she'd never expected the woman to be a shadowy double agent in the spy-ridden underworld. Nor did she anticipate falling for the very vampire who wanted her mother destroyed. Like his name, Striker Dark was ruthless and the sexiest thing Takala had seen in both worlds. Her white-magic power and her willpower was defenseless against him. But, Takala didn't know the long-dead passion she roused in him could end her mortal life. For centuries, Striker had denied himself human blood, but now Takala had resurrected that bloodlust and only hers would satisfy him.
