The United States of America is one of the most diverse countries in the world. More than 323 million people of different faiths, cultural, and ethnic groups live here. I See the Sun in the USA follows Stella, a young girl from Los Angeles, who is helping her mother make a video about diversity and families living in the United States. They visit Mount Rushmore, a National Park in South Dakota, where Stella meets several children from different parts of the country. They each tell her about their lives and Stella imagines what their days are like.
Readers will learn about similarities and differences with each family depicted in the book. Rosa lives in Alabama; Jamal lives in Massachusetts; Kristin lives in Iowa; Martha is a Lakota Indian and lives on the Cheyenne River Reservation in South Dakota. Each child describes a typical day in their life to Stella and is supported by colorful collage illustrations. An illustrated family tree is also provided that offers some insight into where these families each originated.
