Eli and Sarel by Shiloh Walker

After three long centuries of aching loneliness, Elijah Crawford, Hunter of the Council, has finally found a woman. Maybe she can replace the obsession he has for Torrance Reilly, the wife and lover of his best friend. Sarel is a lean, red-haired, wild-eyed witch with a soul to match his. She has a thirst for justice, and a yearning for a love to fill the void inside her. Sarel has been searching for Elijah. She is here now, prowling his grounds, waiting to get into his house. Sarel has come to kill him.
