"In the future, humans trigger a nuclear winter that lasts for hundreds of years. Water levels rise. The shape of the world changes. When the world recovers, vampires emerge from the darkness. Their discovery leads to a war for supremacy ... until synthetic human blood is created, ushering in a period of peace and prosperity. And the world changes yet again. Vampires begin morphing into væmpires, warm-blooded creatures with an insatiable hunger for cold vampire blood. There is no rhyme or reason as to who morphs -- male or female, old or young, from one end of the world to another -- no vampire is safe. And no human is safe, either, because these væmpires aren't interested in coexistence. They want three things: the eradication of humanity, the enslavement of vampires, and their ascension as the dominant species on the planet."--Back cover.
