The horrifying true story of the decades-long poisoning of a small town and the definitive exposé of asbestos in America-told by the Pulitzer Prize-winning journalists who broke it.

In a valley in Montana, the U.S. has spent millions of dollars removing toxic residue from a town that had lain pristine for ages. Until the last century, when the dust came down like a snowstorm. That dust turned a paradise into the worst of America's killing fields, a name at the top of the list that includes Love Canal and Woburn. A place now known to be deadlier than all the rest: Libby.

An Air That Kills is told through the eyes of the men and women who fought back-among them, a woman who watched more than forty members of her family succumb to asbestos; a miner who worked there and carried the poison home; and an EPA investigator who battled not only one of the world's most powerful corporations but also his superiors in Washington. It is the first book to reveal how deeply asbestos has embedded itself into the texture of America: how many people have died or are dying; how the industry and government repeatedly ignored the danger; and how, for many Americans, the dying is not over. It is a suspense story with real American heroes at its heart and one of the most importants works of environmental journalism in years.
