Two Native American cousins find their friendship tested when one moves from the city to the Rez.Amanda loves purple, while Kara's favorite is pink, but "they agree that sunflowers are beautiful, powwow dancing is fun, and chokecherry jam on toast is the best." When the time comes for Kara's family to leave, both girls' parents assure them that the family will be together again next summer at the reunion. A year passes, and the cousins miss each other very much but keep in touch by phone and through letters. When it's time for the reunion on the reservation, the families make preparations: Amanda's family packs and gets the GPS set for the two-day drive; Kara's family makes welcoming signs, and her dad hangs a picture of the family tree. But the girls are nervous: Will they still be friends? In an author's note, Goodluck explains that in the past, many Native families have faced separations; she cites the Indian Relocation Act of 1956 as one cause. Nevertheless, she emphasizes that they still maintain close relationships due to shared family and tribal values. This matter-of-fact yet poignant story brings that bond to vivid life as the girls realize that no matter what, they are "forever cousins." The illustrations rely on a muted palette and feature appealing characters with large heads. Cultural references are scattered throughout, like the dolls made by the girls' magúu (grandmother), powwow dancing, and a Hidatsa naming ceremony. Children facing separations of their own will find this reassuring. (This book was reviewed digitally.)A sweet story of friendship, family, and community. (Picture book. 4-7)
