Blood of Gold

Terrill was the most ruthless of vampires, but over the long centuries of his existence he has evolved into a Golden Vampire, renouncing violence, able to walk among humans and in sunlight.

What he didn't know-what no one knew-was that the evolution was directed by forces bigger than himself.
Terrill and others of his kind have evolved into a higher form of vampire, but another type of vampire has emerged, too. Shadow Vampires can walk in sunlight, for they carry the darkness with them, in their souls and their bodies.

And they are determined to destroy everyone in their way, especially the Golden Vampires... who are the only ones who can stop them.
