What is the author's style in A Step from Heaven by An Na?

The language of the novel is child-like in the beginning peppered with Korean vocabulary. One-word sentences convey a remarkable amount of emotion and exposition as the child narrator attempts to express herself. After the narrator arrives in America with her family, words are often spelled phonetically. The reader must slow down to understand the meaning. The familiar Uncle Tim becomes ......... in Young Ju's ears. This technique demonstrates the newness and the frustration Young Ju feels when working to learn a new language. She comments that Uncle Tim's mouth also has difficulty making their words.
