Evette is a nature-lover full of crafty ideas for reusing and upcycling clothes. When she finds a vintage swimsuit in Gran E's closet, she also uncovers a family secret that could explain why her mother's family, which is Black, and her father's, which is White, don't spend time together. When she visits the river where her grandmother used to swim, she realizes how polluted it's become. She rallies her new friends Makena and Maritza along with her whole family for a cleanup day. She's determined to heal the river--and maybe even heal the division in her family. But will it work? The book includes reader questions, an essay by the author on growing up biracial, and ideas for helping the planet and fighting racism.
