Vampires Of The Eight

Not everyone knows their blood type. But, if you were a vampire, it would mean the difference between life and death. Two thousand years ago, a stranger infected eight pregnant women that caused eight different blood types of vampires to be born. As a result, not all vampires can drink blood from any human. O negative vampires can only take blood from O negative humans, while AB positives can drink blood from any human. And every hundred years, the stranger returns and infects eight more expectant women on May fourth at seven thirty-three in the morning. However, this May comes and goes, but the stranger doesn't show up, and only one vampire leader is worried. When Doctor Shelly Leadstone, an eminent enzymologist, creates an enzyme that strips the protein off of red blood cells, thereby creating a universal blood type for all the eight blood types, not all vampires are happy. The enzymes are stolen, which creates rifts in the blood groups. As each faction of vampires tries to deal with each other, two leaders emerge in a cat and mouse game where the ending could spell doom for the entire eight vampire blood types.
