In 2041, vampires are discovered and humanity is thrust into a blood-soaked battle for supremacy.
Seven years later, the Human-Undead War rages on. Brian Koltz, the lead scientist, and negotiator for the Undead Relations Committee, believes he holds the solution to peaceful cohabitation. However, he is unable to recreate the platelet mushroom due to its mysterious origin and government disapproval of using a human body as its engine.
