The Overstory Summary, Characters and Themes

“The Overstory” by Richard Powers is a novel that interconnects the lives of its characters through their unique relationships with trees and the natural world.

It’s a story that explores how separate lives and actions can collectively impact the environment, thus creating a tale of human emotion, ecological awareness, and the enduring power of nature.


The story begins in the mid-1800s with Jørgen Hoel, who plants chestnuts in Iowa, leading to a tradition of photographing the surviving tree across generations. Tragically, Jørgen’s descendant, Nick, finds his family dead after a gas leak.

Shifting continents, we meet Ma Sih Hsuin (Winston Ma), who migrates from China to America, bringing treasured jade rings and an ancient scroll. In Illinois, he plants a mulberry tree, symbolizing his new roots. 

Tragedy strikes again when Winston dies by suicide, leaving behind his wife and daughters, including Mimi, who later becomes an environmental activist.

Then there’s Adam Appich, a curious child fascinated with insects and social psychology, whose life takes a turn when his sister goes missing. 

Adam’s story intersects with Ray Brinkman and Dorothy Cazaly, a lawyer and stenographer duo whose rocky relationship leads to a spontaneous marriage and a unique tradition of planting new flora annually.

Douglas Pavlicek’s life is a rollercoaster, from surviving a plane crash thanks to a banyan tree, to witnessing the devastating effects of deforestation in Oregon, sparking his environmental activism.

Neelay Mehta, a child prodigy in computer programming, faces a life-altering accident that leads him to design immersive computer games, eventually focusing on conserving the natural world.

Patricia Westerford, a deaf botanist, discovers the communication between trees, facing initial skepticism but eventually gaining recognition for her groundbreaking research. Her life takes a turn when she meets Dennis, with whom she forms an unconventional yet fulfilling relationship.

Olivia Vandergriff’s near-death experience leads her to abandon her carefree college life for environmental activism, eventually joining forces with Nick at the Hoel farm.

As the narratives intertwine, the characters’ lives are marked by love, loss, and a shared mission to protect the natural world. Their paths converge in a dramatic climax involving arson and personal sacrifice, profoundly impacting each character’s trajectory.

In the novel’s resolution, each character finds their own way to contribute to the greater good, from Nick’s thought-provoking art to Mimi’s therapeutic practices and Patricia’s seed vault project. Neelay’s new game aims to educate about Earth’s biome, while Adam faces the consequences of his actions.

Key Themes

1. The Interconnectedness of Humans and Nature

At its heart, “The Overstory” underscores the deep, often overlooked connections between humans and the natural world. 

Trees, central to the novel’s narrative, are not just background characters but are pivotal to the story’s progression and the lives of its characters.

This theme challenges the reader to reconsider their relationship with the environment, emphasizing that our actions towards nature have direct, sometimes irreversible, consequences on our own lives.

2. Environmental Activism and its Consequences

The novel doesn’t shy away from the harsh realities of environmental activism. Through characters like Mimi, Douglas, and Olivia, we witness the emotional and physical toll of fighting for ecological preservation. 

Their journeys through protests, acts of civil disobedience, and even extreme measures like arson, paint a vivid picture of the sacrifices and risks environmental activists often face. 

This theme serves as a poignant reminder of the urgency of environmental issues and the lengths to which individuals are compelled to go in the face of apathy or opposition from society and governments.

The novel portrays trees and forests as entities that endure and outlive generations of human life, reminding us of the longevity and persistence of the natural world. 

This theme is beautifully encapsulated in characters like Ray and Dorothy, who allow their backyard to grow wild, witnessing the relentless growth and transformation of nature.
