Birnam Wood Summary: The Deep Dive
Spoilers ahead.
In Eleanor Catton’s Birnam Wood, a landslide buries the Korowai Pass highway, killing five people and isolating Thorndike.
Mira Bunting, founder of the guerrilla gardening collective Birnam Wood, spots an abandoned farm and sneaks in to scout it. There, she encounters Robert Lemoine, an American billionaire who claims he is building a bunker.
Lemoine is actually running an illegal rare-earth mining operation inside Korowai National Park. His drilling caused the landslide.
He offers Birnam Wood $100,000 to farm the property as a cover. At a caucus meeting, Tony Gallo opposes the offer, calling it blood money. Mira and others argue for survival, and Shelley Noakes casts the deciding vote to accept.

Tony resigns and travels to Thorndike to investigate. Meanwhile, Owen Darvish, the farm’s owner, is knighted. His wife Jill reveals they sold the farm to Lemoine.
Owen grows suspicious after Tony emails him about a radiometric survey. He flies to Thorndike unannounced.
At the farm, Birnam Wood has set up camp. Lemoine gives members LSD.
A distraught Shelley, tripping and fleeing, accidentally hits Owen with a van, killing him. Lemoine convinces Mira to help stage the death as a car accident. They push Owen’s SUV off a cliff.
Tony discovers Lemoine’s mining site: chemical boreholes, dead wildlife, and armed mercenaries. He photographs everything but is injured escaping.
He reaches Mira and shows her the film. Lemoine captures them both. Lemoine decides to poison the entire collective with 1080 and frame Tony as a murderer-suicide.
Jill Darvish, suspicious, arrives with a rifle. She finds the youths dead or dying and Tony and Shelley bound.
She shoots Lemoine dead, but his bodyguard kills her. Before dying, Jill cuts Tony’s bonds. Tony crawls to the mining site and sets it on fire.

Memorable Quotes
“Like all self-mythologising rebels, Mira preferred enemies to rivals, and often turned her rivals into enemies, the better to disdain them as secret agents of the status quo.”
“Five dead was nothing, thought Lemoine. Five dead, in the scheme of things, was basically no dead at all.”
“You’re literally getting into bed with the enemy, you’re violating every principle this group was founded on – am I really the only one who sees that?”
“Doomsteading, Sir Owen said. That’s what they call it. Bunking down for the end of the world. They’re doomsteaders, that’s the word.”
“The real choices that you make in your life, the really difficult, defining choices, are never between what’s right and what’s easy. They’re between what’s wrong and what’s hard.”
“That is a song, Jill, that knows when it is done.”
