This slim entry in the Young Heroes series introduces Julia Butterfly Hill, the environmental activist who spent 738 days in a California redwood tree to protest a lumber company's clear-cutting practices. It follows the young activist from her teen years, when she took a stand against abusive classmates and chose a vegetarian diet, to her initial connection with the Earth First movement, her famous "tree sitting" stints, and continued environmental activism. Lynette's lively account zeros in on intriguing details, from the way Hill handled bathing and urination in the tree to earth-friendly practices that readers can emulate. Sharp color photos will further pique interest, and source notes, suggested reading, and a glossary of terms that appear in boldface throughout the text add support.
