London, 2030. We follow the life of Iris from childhood to adulthood through her diaries. She has been madly in love with Nick since high school. But the world around them is falling apart due to the climate crisis. As Iris's and Nick's story progresses, so does the destruction on Earth. Iris is a young girl leaving in London with her mother. All she wants is Nick, who totally ignores her until, well, he doesn't. But life on mid-century Earth is hard. Heatwaves following freezing winters. Millions of refugees running to escape starvation. Forests burning and ice melting. Violent protests on the streets, brutally suppressed by the authorities. And finally, a deadly ancient virus. When all hope seems lost, unexpected help arrives from afar. But things may not be as they seem. And mistakes made, either personal or collective, may not be forgiven. People, places, and species may be lost. But forgotten, they will be not.
