Count of Saint-Germain

Chelsea Quinn Yarbro's long-running historical vampire series follows the vampire Count Saint-Germain across roughly two dozen centuries and settings, from Hotel Transylvania's Revolutionary-era Paris onward through Byzantium, Renaissance Italy, feudal Japan, and beyond. Each novel is a largely self-contained historical novel grounded in real events and period detail, with Saint-Germain recurring as a centuries-old witness and occasional participant rather than driving one serialized plot. Yarbro pairs the vampire conceit with meticulous historical research across the series' 28-plus volumes.
