Booker winner Catton (The Luminaries) returns with a tragic eco-thriller of betrayed ideals and compromised loyalties involving a collective of guerilla gardeners in New Zealand. The group, Birnam Wood, sets its sights on a farm in Korowai National Park after a landslide maroons the isolated township of Thorndike, and three personalities vie for control. As matriarch Mira Bunting, 29, uses a series of aliases to scout and buy the land, her duplicity brings her into conflict with the younger Shelley Noakes, whose own beliefs are further strained by the return of ex-member Tony Gallo, a would-be journalist with an ax to grind regarding some of Birnam's rhetoric (in a scene of stellar dialogue, a group of members, all white and economically privileged, object to Tony's claims that intersectionality and polyamory are capitalist concepts). Mira's and Shelly's designs on the farm are complicated as they run afoul of Robert Lemoine, an amoral American billionaire suspected of murdering his wife, who has secretly purchased the land and agrees to fund Birnam Wood's occupation as a cover for his mining operation (Robert's work had caused the landslide, a detail he's trying to keep under wraps). As Mira plays into Robert's hands, Tony goes on the warpath, and their various schemes collide in a shocking crime."--Publisher marketing.
