What is the author's tone in Mr. and Mrs. Bo Jo Jones by Ann Head?

The author's tone and prose as July seems appropriate for a young woman going through great changes with great uncertainty. Frequently July's thoughts will have contradictions, or she will leap from one idea to another unrelated one quickly. Her emotions are also ambivalent, loving Bo Jo one moment and just wanting to get away from him the next. The author is quite skillful and realistic in this regard. Contemporary youth vernacular - Bo Jo is a "go go guy," July felt "snowed," other kids in school are "way out" - help to create the illusion that July is a real girl from the late 1960s telling her story.
