After enduring years of torture from the vampire horde, Lachlain MacRieve, leader of the Lykae Clan, is enraged to find the predestined mate he's waited millennia for is a vampire. Or partly one. This Emmaline is a small, ethereal half Valkyrie/half vampire, who somehow begins to soothe the fury burning within him.
Cole's Immortal After Dark books are wonderfully addictive! I bought one to read then went back and bought the rest within the month. They are very fun to read; I love the characters. Next to Sherrilyn Kenyon's books, I would highly recommend Cole's series.
