This was by a writer who had also made books about a plague that was found by genetically engineered humans deep underwater. Later books in that series followed the women who discovered the plague through an apocalyptic USA in search of vengeance (?).
In the spaceship story, they got their energy though some kind of quantum bridge from a station in close orbit to the Sun. The vampire character had a console where every indicator was a screaming face of some kind, because that was the easiest way to gather information for him. In the end it is (implied?) that Earth has been taken over by vampires.
