The Overstory

A Novel Structured Like a Tree

Richard Powers divides The Overstory into four sections named for parts of a tree: Roots, Trunk, Crown, Seeds. Roots introduces nine separate human stories — a multigenerational American family and their chestnut tree, a soldier who survives a fall from the sky because of a banyan, a computer scientist who can hear trees talking, a war veteran, an activist, a student brought back from death by a vision — each complete in itself, each apparently unconnected to the others. In Trunk, the stories begin to converge. In Crown, they meet. In Seeds, they scatter.

The structural conceit is not merely decorative. It is an argument: that the way human consciousness typically organises narrative — individual, causal, temporally compressed — is precisely the kind of consciousness that cannot perceive the forest. Trees operate on timescales that make human lifetimes look like a season, and the novel’s form is an attempt to build a different kind of attention in the reader, one that can begin to perceive things at arboreal scale.

What the Science of Trees Does to the Novel

Powers is one of American fiction’s most technically serious novelists, and The Overstory is built on the science of forest ecology — specifically the research of scientists like Suzanne Simard, whose work on mycorrhizal networks demonstrated that trees communicate and cooperate through underground fungal webs, sharing nutrients and chemical signals. One of the novel’s nine protagonists, the scientist Patricia Westerford, is a version of Simard: a researcher whose findings are initially dismissed as anthropomorphism and later vindicated.

The science transforms the novel’s moral stakes. If trees are not passive objects but agents with memories, relationships, and something that functions like choice, then the destruction of forests is not property damage but something closer to murder — a claim the novel makes explicitly and tests against the lives of characters who are willing to break the law in its defence.

Nine Lives and One Argument

The characters Powers assembles are carefully differentiated by class, background, and relationship to the natural world. Their convergence in the Tree Trunk section — at an old-growth redwood sit-in, at protest camps, in legal battles and bombings and escapes — is the novel’s most propulsive section, and it asks genuinely difficult questions about political violence, personal sacrifice, and the relationship between love and efficacy. The characters who commit to radical action do not become heroes in any conventional sense. Their actions have consequences that Powers refuses to resolve into clear moral judgement.

The Pulitzer Prize and the Novel’s Ambitions

The Overstory won the 2019 Pulitzer Prize for Fiction, a recognition that its ambition and achievement are inseparable from its subject matter. Powers is asking American literary culture to expand its definition of what a subject can be — to include the non-human, the geological, the arboreal — and the novel’s formal and narrative ambitions are in service of that expansion. It is a book that wants to change how its readers see when they look at a tree. For many readers, it succeeds.

Our rating: 4.2/5

A Novel With Trees as Protagonists

The boldest thing about The Overstory is its decision to decentre human beings. Richard Powers structures the novel like a tree — roots, trunk, crown, seeds — and gathers nine human characters whose separate stories gradually converge around the fate of forests, but the real protagonists are the trees themselves, rendered with a scientific richness and a sense of time so vast that the human dramas come to feel small and brief by comparison. That reversal of scale is the novel’s argument as much as its form: it asks the reader to imagine a world in which the slow, ancient, interconnected lives of trees matter as much as our own.

Science Turned Into Wonder

Much of the book’s power comes from how seamlessly Powers folds real botany and forest ecology into his fiction. The discoveries that trees communicate and cooperate through underground networks, that forests behave like single interconnected organisms, that individual trees can live for thousands of years — these are presented not as lectures but as sources of genuine awe, and they change how many readers see the trees outside their own windows. Powers’s gift is to make the science feel like revelation, and to use it to mount an urgent argument about humanity’s relationship to the living world.

Ambition and Its Risks

The Overstory is unashamedly a novel of ideas with a cause, and that ambition divides readers. Admirers, including the Pulitzer committee, find it overwhelming, visionary, and capable of altering how one sees the natural world; sceptics find its activism heavy-handed and its later sections more polemic than fiction. Both responses are fair: this is a book that prioritises its argument, and readers who want their fiction free of advocacy may resist it. But the ambition is also what makes it memorable.

Who Should Read It

This is a long, intellectually demanding, and emotionally expansive novel for readers willing to be challenged and changed by what they read. It rewards patience — the nine separate stories take time to cohere — and it asks the reader to care about something larger than the usual human concerns of fiction. For those open to it, The Overstory is among the most ambitious and moving novels of its decade, a book that genuinely succeeds at its enormous aim: to make the reader feel the aliveness, and the loss, of the forests.
