What if a microbe made people sick or killed them based on their history of immoral actions? Virologist Allison Daws' newly created virus does exactly that. Beginning in New Mexico, she infects a predatory local there and proceeds to travel the country, testing increasingly contagious strains. Hot on her heels are a federal agent with strong, if jaded, morals of his own, a local cop with a personal connection to the virus's first victim, and a world-renowned virologist who is by turns fascinated and horrified by what the disease can do. All three of them know they must catch up to Daws before she releases her most communicable form of the virus, and the world is changed permanently. By degrees curious and deadly, The Moral Virus poses controversial questions of human nature, science, and what it means to be responsible for spreading good or evil.
