It's the summer holidays, and thirteen-year-old Luke has just had his life turned upside down. First his older sister Rose moved 'across the road' - where a community of climate rebels are protesting the planned airport expansion - and now his dad's gone too. Dad only went to get Rose back, but he's out there building totem poles out of old furniture and wearing sandals and drinking mead (whatever that is) with the best of them . Luke is determined to save his dad, his sister and his summer. So how does he find himself at the top of a tree refusing to leave until the bulldozers stand down? A fresh, funny, heartfelt look at this generation's must-win battle: one earth, one chance.
