completely forgot about Christine Feehan's Carpathian Dark Series - she makes the distinction between "Carpathians" (an old race of long-living people with telepathic abilities who drink blood and are burned by sunlight) and "vampires" (Carpathians gone over to the dark side). It's a really good series, starts with Dark Prince - about the Prince of the Carpathians falling in love with a human. The world building is good as are the characters and there's an underlying plot line that runs through all the books. The most recent books in the series (there are 25+) are a little nauseating in their use of the "Carpathian" language (aka random foreign words thrown in) but the plot line keeps me reading.
