From The Grey House:
Most of the women in his life started out as human, but the only woman he had ever taken after a fight was his sire, Lorraine. She never showed any signs of fighting; vampires hardly ever did. Vincent took a deep breath, letting it out slowly through his nose. He closed his eyes; he could smell Natalia’s blood and sweat. It was coming off her in waves. The scent of blood was arousing, but he didn’t want her like this.
