I never would have thought it was possible to pull off vampires and alien invaders in one shot, but it appears I was wrong. I have also read "In Conquest Born" and the Coldfire Trilogy, and this is undoubtably my favorite. The story takes place in a future human society where our main character is a vampire far too modern and scientific to believe in such archaic fantasies as vampires. He does, however, believe in space-aliens, as Earth has been ruled by alien invaders for the past three-hundred years. Friedman's characters are, as usual, completely real, and I would love the chance to get my hands on a sequel if there were one.
