The Passage by Justin Cronin

The Passage is a long (766 pages) novel set in the near future. It's really two stories: first, a deadly disease sweeps the North American continent, wiping out the majority of the population and leaving many of the survivors less (or more?) than human. The second part is the story of one band of surviving humans, who are isolated, fearful, and ignorant of what is going outside their own community. It's an engrossing read, although I felt it ended too abruptly and without resolving many of my questions.
