St. Germain

 Chelsea Quinn Yarbro has written more than twenty historical horror novels about her vampire hero, the Count Saint-Germain.  The Saint-Germain books, which can all be read independently, take place in many different parts of the world and many different periods of history.  The Count has seen the best and the worst humanity has to offer, from Mongol hordes to Egyptian pharaohs, from the construction of St. Petersburg to the rise of the Nazis.  Lush with history and rich in sensuality, the Saint Germain series is the longest-running series about a vampire in modern literature.
