Formosan Vampire by Amadeus Rockefeller

A foreign prisoner waiting on Taiwan’s death row is believed by some to be the murderous and powerful leader of a legion of vampires called the Dark Order. However, no one knows why this creature allowed itself to be captured and consequently executed. It isn’t until Eunice Wang, a young paralegal, visits the prisoner before his execution that he tells an epic historical tale about the life that led him to become the Formosan vampire king, reigning for thousands of years over the island kingdom. A fearsome civilization that vanished mysteriously at the beginning of the 20th century. A civilization that would surpass the terrors and bloodshed of all since ancient times.
