Birnam Wood by Eleanor Catton (Granta)
Mira and Shelley: best friends, climate comrades and co-founders of a guerrilla gardening collective in desperate need of funds to carry on their righteous work - in this case, illegal squatter plantings on private farmland seemingly abandoned after an earthquake on New Zealand's South Island.
Relations between Mira and Shelley are already rocky when Tony, a former member of the Birnam Wood collective, reappears with a straggly new beard and an old crush on Mira. But this is not a story about love. It is a story about power and greed and blind virtue, and when a mysterious billionaire enters this already tense picture and offers the group financial support, Mira, Shelley and Tony find themselves on a collision course between principles and practicalities, money and morals, compromise and consequences. Deals with the Devil will be made.
