When Dr. Lou Welcome's friend Cap Duncan injures his leg, surgeons manage to save it. But the open wound is the perfect breeding ground for a deadly microbial invader committed to eating Cap alive from the inside out. Meanwhile, hundreds of miles away, a teenaged girl is fighting for her life against the same bacteria. The germ is resistant to antibiotics, and the government scientist tasked with finding a cure has been kidnapped. Turning to the Centers for Disease Control for help, Lou Welcome uncovers a link to a shadowy group known as One Hundred Neighbors.
One Hundred Neighbors will stop at nothing to further their agenda, and now Lou must stop an epidemic, save his best friend—and face his own most terrifying demons.
