The Passage begins in the near future and details an apocalyptic and, later, post-apocalyptic world that is overrun by vampire-like beings who are infected by a highly contagious virus. What begins as a project to develop a new immunity-boosting drug based on a virus carried by an unnamed species of bat in South America eventually becomes the virus that transforms the world. The novel begins in 2016 and spans more than ninety years, as colonies of humans attempt to live in a world filled with superhuman creatures who are continually on the hunt for fresh blood.
