A book about the big questions of the future. Nora, almost sixteen, is a smart and proactive girl. She thinks about the environment: climate change, species extinction, and the threats to our planet. Together with her friend, she starts an initiative that develops measures to preserve the Earth's atmosphere. However, one curious aspect of Nora's life is that in her dreams, she receives messages from her great-granddaughter Nova from the year 2084. In Nova's world, sea levels have risen, climate refugees roam, camels graze in the north, and countless species have gone extinct. Can Nora ensure that the ecological catastrophe of the future is prevented in her time? And how can her dreams help her with that?.
