Told in Rundell's unique voice and inspired by her expedition to the Amazon and Eva Ibbotson's beloved Journey to the River Sea, this is the must have book. After crashing hundreds of miles from civilisation in the Amazon rainforest, Fred, Con, Lila and Max are utterly alone and in grave danger. They have no food, no water and no chance of being rescued. But they are alive and they have hope. Award-winning author Katherine Rundell returns with a new story of adventure, survival and bravery.
