Wolf in the Night - N. J. Walters

Driving home from a trip, Emma Matheson is run off the road in an abduction attempt. Seems the alpha of her father's former pack never forgave his defection. To settle the old score, he plans to force her to mate with a male of his choosing—his son, Dmitri.
Dmitri Gribkov wants no part of his father's revenge. A loner by choice, nothing has prepared him for sexy, stubborn Emma. He'll do whatever it takes to protect her—even if it means losing her.
Determined to control her destiny, she does her best to escape, even as the attraction between her and Dmitri sizzles. Doesn't take long for her to realize this huge, sexy wolf is a protector at heart.
Tracking and killing are what he does best. Before this is over, he'll have blood on his hands, but winning her love will be the hardest battle.
