The Overstory

Powers's boldest move is formal, not thematic: the novel is divided into "Roots," "Trunk," "Crown," and "Seeds," mimicking a tree's own anatomy, so that nine ostensibly separate character studies gradually fuse into shared plot before scattering back into consequence — the structure itself argues that individual human stories are subordinate branches of something larger and slower, exactly the decentering claim the book makes about human consciousness relative to plant life. Patricia Westerford, the dendrologist ridiculed early in her career for suggesting trees communicate and cooperate, functions as the novel's scientific conscience and its clearest self-portrait: an outsider insisting an entire field has been thinking at the wrong scale.

Each major character is "converted" by a tree encounter that reads almost as a religious experience — Nicholas Hoel's family chestnut, photographed once a month for nearly a century; Mimi Ma's mulberry; Douglas Pavlicek's fig, which saves his life in Vietnam — and the accumulation makes a case that reverence for trees isn't sentimentality but a corrected perception, a return to a relationship humans abandoned somewhere around the industrial revolution. Time itself is the novel's real subject: trees operate on a scale of centuries that dwarfs any individual activist's lifespan, and Powers structures long stretches of the book to feel correspondingly slow, forcing readers into something like arboreal patience before the plot's human urgency reasserts itself.

Powers doesn't just write about trees, he tries to write from a perspective adjacent to theirs — omniscient passages step back from any single character to render forests as networks, chemical signals, and mycorrhizal conversations that dwarf the human plots threading through them. It's a deliberate rebuke to the assumption, built into most fiction, that only human interiority merits sustained narrative attention, and the novel's critical reception often centered on whether this experiment succeeds or merely gestures at succeeding — a debate the book itself seems to welcome as part of its argument.

Patricia's late-career turn toward seed banking — patiently archiving genetic diversity against a collapse she expects to outlive any activism — and Nick's return to land art, arranging materials into massive earthworks visible only from above, both function as answers to the novel's activist thread: if direct action's costs are severe and its victories uncertain, these quieter, generational forms of stewardship offer another register of resistance, one measured in centuries rather than news cycles.
