About one hundred million years ago when the dinosaurs were disappearing from the earth, flowering plants appeared. These two things are related: flowering plants created more food for the emerging, warm-blooded mammals. This book envisions the existence of the very first flower on earth for children; it tells of her hardships: of being tiny and seemingly insignificant, different from the giant plants, of her friendship with a dinosaur and a mouse, the loss of her flower and the emergence of a berry which contains the seeds for more flowers.
