When Autumn Peltier was 12 years old, she made headlines for speaking out about the lack of clean water in Indigenous communities. Since then, she's become a world-renowned water rights advocate. Her inspiring story is now being told in a new children's book, Autumn Peltier, Water Warrior, written by New York Times-bestselling author Carole Lindstrom, with hopes of inspiring young readers to join in the movement for change.
