The Downfall of Caine

This is a biography of Caine from my story The Human Mate. It includes his point of view of The Human Mate too.
Caine is the first known vampire. After losing his sister to a werewolf attack he has made it his life mission to kill all werewolves and their mates. He has killed many. But when he goes after a werewolf named Bryan and his human mate Avery will he succeed in killing them or will they kill him?
