Featherweight. Hallow Brothers, #6

He was just a hapless victim in a bar. At least that was what vampire hunter Dakota Ross thought until the sexy smartass she was drawn to protect was able to keep toe to toe with her as they fought. When she finds a strange tattoo etched into her back after a night of intense, passionate sex, she discovers that he is Ezekiel Hallow, one of seven werewolf brothers. They team up to find Black, who has killed her husband and has the Book of Elvesayd, an artifact Ezekiel desperately needs.
Each step on their journey becomes more deadly as they get closer to Black. How far will they go to find the Book? Can Dakota stop Black from taking the life of another man she loves?
