This is a dystopian story unlike any I've read. The 1st half is especially creative. We're given a world decimated by nuclear war, a populace so wasted by apparent radiation sickness that a constant supply of blood is needed from healthy people, a caste system based on blood type, a corporation functioning as the government, &three female protagonists who learn the truth & fight to bring down the bad guys. 2nd half is not as good but still a pick.
