New York Magazine called this "A very clever, absurdly fun novel that reads like a cross between a locked-room mystery, a spaghetti Western, a game of Sodoku, and Edwin Drood."

The publisher calls this "Shakespearean in its drama, Austenian in its wit, and, like both influences, fascinated by what makes us who we are. A landslide has closed the Korowai Pass on New Zealand’s South Island, cutting off the town of Thorndike and leaving a sizable farm abandoned. The disaster presents an opportunity for Birnam Wood, an undeclared, unregulated, sometimes-criminal, sometimes-philanthropic guerrilla gardening collective that plants crops wherever no one will notice. For years, the group has struggled to break even. To occupy the farm at Thorndike would mean a shot at solvency at last. But the enigmatic American billionaire Robert Lemoine also has an interest in the place: he has snatched it up to build his end-times bunker, or so he tells Birnam’s founder, Mira, when he catches her on the property. He’s intrigued by Mira, and by Birnam Wood; although they’re poles apart politically, it seems Lemoine and the group might have enemies in common. But can Birnam trust him? And, as their ideals and ideologies are tested, can they trust one another?"
