When Sona learns about the climate crisis at school, she worries nobody is doing enough to combat it. So she takes up the challenge herself! But her family isn't amused when Sona suddenly gets rid of her sister's diapers and turns off Thatha and Paatti's cooling fan during their nap. Sona finds a better way to implement change, at a family meeting where everyone helps make a list of ways to conserve. Energized, Sona sets her sights on the rest of the neighborhood. When she learns many of the kolams--traditional art that people draw in front of their homes to celebrate the festival season--are not eco-friendly, she makes plans for some even bigger changes. Can Sona convince everyone to get involved--even her own strong-willed grandmother? Charming illustrations bring to life this heartening story and its delightfully eager main character, who is sure to inspire young environmentalists. Back matter includes a vocabulary list and a lesson on how to draw your own kolam.
