A young student receives a family tree assignment in school, but she can only trace back three generations. Grandma gathers the whole family, and the student learns that 400 years ago, in 1619, their ancestors were stolen and brought to America by white slave traders. But before that, they had a home, a land, a language. She learns how the people said to be born on the water survived. With powerful verse and striking illustrations by Nikkolas Smith, provides a pathway for readers of all ages to reflect on the origins of American identity.
