Earth is a fascinating planet. In the vast, infinite universe, it remains the only known place where life has emerged. But how did that happen? Eva is small, and her problems feel huge. She’s afraid of the wolves that seem to be everywhere, always lurking. But she has her mother—someone who understands her completely. To comfort Eva, her mother tells her three gripping stories from the history of life on Earth, where even the smallest and weakest have found ways to overcome the strong. Like Earth itself. It’s not as massive as Jupiter, as dazzling as Venus, or as stunning as Saturn, yet it’s the only planet that sustains life. Or the tiny but fearless cell—without it, there would be no plants, no animals, no life at all. And then there’s the prehistoric squirrel, an unlikely survivor in a world ruled by dinosaurs. Will little Eve also find the courage to stand up against the odds?
