Quick Facts

Short Summary

A landslide on the Korowai Pass isolates the Thorndike region, opening an opportunity for the guerrilla gardening collective Birnam Wood to occupy the abandoned Darvish farm. Founder Mira Bunting scouts the property using an alias, unaware that billionaire Robert Lemoine has been secretly surveilling the area and already bought the land. Former member Tony Gallo returns with a suspicious $100,000 grant, which Mira and reluctant member Shelley Noakes accept. The collective’s idealistic mission clashes with Lemoine’s hidden ambitions—a secret radiometric drone survey for mineral deposits in the national park. When Sir Owen Darvish unexpectedly returns home, Shelley accidentally hits him with a van. Lemoine orchestrates a cover‑up, staging Owen’s death as a car accident while Tony discovers the mining operation and barely escapes with his life. The novel explores ideological conflict, surveillance, environmental exploitation, guilt, and class power.

Full Summary

Birnam Wood opens with a landslide on the Korowai Pass that cuts off the small town of Thorndike. Mira Bunting, the pragmatic leader of the activist collective Birnam Wood, sees the suddenly isolated Darvish farm as a perfect site for their guerrilla gardening. Using a false name, she scouts the property and finds a plane on the grass—a sign that someone else is interested. Meanwhile, Shelley Noakes, a longtime member, is quietly planning to leave the group. Tony Gallo, a former member now a freelance journalist, returns from abroad and offers a $100,000 grant. Mira and Shelley accept, then head to Thorndike. The chapter also introduces Robert Lemoine, a billionaire who has been covertly monitoring the region and recognises Mira’s deception.

In Chapter II, Sir Owen and Jill Darvish host the Mulloys for dinner, awkwardly revealing the secret sale of their farm to Lemoine. Tony hikes to Thorndike to spy on the property and encounters a security guard near a fenced mobile‑phone tower; the guard appears to carry a concealed handgun. Posing as a journalist, Tony calls Sir Owen, who inadvertently mentions a radiometric drone survey by a company called Autonomo before hanging up. At the Birnam Wood camp, Mira reflects on Tony’s expulsion from the collective and the moral cost of Lemoine’s funding. The chapter closes with a tense debate between Mira and Lemoine about apocalyptic preparedness and power.

Chapter III drives the plot to its crisis. Jill Darvish wakes to find her husband Owen missing. Lemoine calls her, then enlists Mira to move Owen’s body and stage a car crash at Korowai Pass. The accident is a cover‑up: Shelley, high on drugs provided by Lemoine, had accidentally hit Owen with the van. Lemoine reports the “accident” to the police and acts as a grieving friend. He then warns Mira and Shelley about a threat in the park. Separately, Tony discovers the secret Autonomo mining operation in the national park. He is chased, jumps into a creek, and escapes with a broken arm and ankle. Back at the shed, the group holds a celebratory dinner, but Mira’s discomfort grows as she realises the depth of her complicity.

A final paratext section, “A Note About the Author,” provides biographical context about Eleanor Catton—her Booker Prize‑winning novel The Luminaries, her debut The Rehearsal, and her screenwriting work—without advancing the narrative.
