Enthrall Me by Tamara Hogan

They say that opposites attract, but this is ridiculous… Vampire journalist Tia Quinn is young (by vamp standards), curious (even by reporter standards) and sitting on some information that could threaten civilization as she knows it. She’s honor-bound to share it with the Underworld Council’s chilly Vampire Second, an ancient vampire more powerful than she can imagine…and who’s hotter than hell. He’s also burdened by duty and taciturn to the point of grimness but when a stalker breaks into her house, Wyland insists on keeping Tia close until the perpetrator is caught.

Wyland’s life is exactly the way he likes it — solitary, calm, predictable. Then Tia moves in, turns his staid bachelor household upside down, and wakes his libido from its hundred-year nap. She’s too alluring, too damn young, and hell on his self-control—especially when she cheerfully informs him the attraction is mutual. But the last time he let his heart overrule his head, his people paid the price. He can’t make the same mistake again. As they work together to neutralize the threat, Tia and Wyland soon realize that not only do opposites attract, but that the end result can be positively magnetic…
