The Cull. In the Blood, #1

The world is thrown into a frenzy when an experimental virus is accidentally released. Highly contagious, its victims suffer a fate worse than death. Bodies ravaged by fever, their numbers increase at a startling rate as they mindlessly roam the streets infecting all with whom they come into contact until their inevitable and swift deaths. Frankie, a businesswoman with a young family, and Henry, a bachelor well on his way to becoming a grumpy old man, find themselves caught in the fallout.
Terror the new way of life, each struggle to survive as society crumbles around them. Hundreds of miles away from one another, they find themselves on a journey to Los Alamos, New Mexico with hopes of finding a cure that, unbeknownst to them, resides within their veins.
