Description Once there was a redwood tree-one of the world's largest and tallest trees, and one of the oldest. And once, born nearly a thousand years after the tree first took root, there was a girl named Julia, who was called Butterfly. When exploring her beloved forest, Butterfly wandered into a grove of ancient trees. One tree had broken branches and a big blue X on the side. It was going to be chopped down. Butterfly climbed up into the tree.A tree wouldn't be cut down if it had a person living in it. This is the story of Julia Butterfly Hill and Luna, the redwood tree she lived in for two years, never once coming down. That is, not until Luna's future was safe.
