The Overstory unfolds in concentric rings of interlocking fable that range from antebellum New York to the late-twentieth-century Timber Wars of the Pacific Northwest and beyond. An Air Force loadmaster in the Vietnam War is shot out of the sky, then saved by falling into a banyan. An artist inherits a hundred years of photographic portraits, all of the same doomed American chestnut. A hard-partying undergraduate in the late 1980s electrocutes herself, dies, and is sent back into life by creatures of air and light. A hearing- and speech-impaired scientist discovers that trees are communicating with one another. These and five other strangers, each summoned in different ways by trees, are brought together in a last stand to save the continent's few remaining acres of virgin forest.

There is a world alongside ours—vast, slow, interconnected, resourceful, magnificently inventive, and almost invisible to us. This is the story of a handful of people who learn how to see that world and who are drawn up into its unfolding catastrophe.
