What is the author's style in The Circuit: Stories from the Life of a Migrant Child by Francisco Jimenez?

The language of the book is very simple and child-like. Since the narrator is a child, the language has a young, simple tone. There are some difficult vocabulary words interspersed throughout the story, but they would be difficult for a child, not an educated high school student. The language is written for a young reader, perhaps a child around ten to twelve years old. However, the language also has a universal quality; it is not too immature for a young adult or an adult reader to enjoy.
