This fast-paced dystopian novel starts with a man-made virus called TD1. Created toward the end of the Second World War by the Nazis, it was to be used against the Allied Forces at a point when Germany was losing the war. However, the mission to unleash the virus by a German U boat failed. Then in 2019 the virus resurfaces and takes over the world, bringing mankind to the brink of annihilation in early 2020. Jack Mercer, an independent international investigator hired by the World Health Organization, races to find the rumored antidote to the virus and save the world. But it means digging up old secrets.
