What is the title of Richard Powers's 2019 Pulitzer Prize-winning novel?

The Overstory is Richard Powers’s 2019 Pulitzer Prize-winning novel.

Published in 2018, the novel connects the lives of several people whose experiences become intertwined through trees and forests. Its structure moves among separate human stories before bringing many of them into a broader narrative about environmental activism and ecological interdependence.

Powers uses trees not merely as scenery but as central subjects with immense timescales and complex forms of communication and survival. The novel contrasts short human lives with the long history of forests and the accelerating effects of environmental destruction.

The title points to the upper layer of a forest canopy and also suggests a larger story rising above individual characters. The book is sometimes categorized simply as an environmental novel, but it also includes family history, science, protest, ethics, and questions about how humans understand the natural world.
