Voted the best children's book on Black History by Mothering magazine, Dr. Angela Sadler Williamson shares a different side of Rosa Parks only known to her family, the Williamson family. Lovingly known as Cousin Rosie, Rosa Parks spent most of her adult life living in the City of Detroit after leaving Montgomery, Alabama in 1957. Cousin Rosie forms many special relationships with young people, especially her young cousin, Carolyn Williamson Green. This book helps continue Rosa Parks' legacy and philosophy on activism by teaching young readers how to become change agents in their community.
