42 Miles by Tracie Vaughn Zimmer

At first, her parent's divorce wasn't too bad since they only lived four blocks apart in Cincinnati, Ohio. But when her father moved into Grandpa's farm after Grandpa died, it was a whole 42 miles away!
JoEllen became two persons: a city girl named Ellen enjoying fashion, baseball, and old movies with her mother during the week and then a country girl named Jo going to the country fair and visiting the bookmobile with her father on the weekends.
Finally, she decides she has had enough and merges the two lives together by introducing her city friends to her country cousin, creating new organic dishes, changing her clothes and hair and spending time enjoying the things she likes most.
The whole coming of age experience is written in simple free verse poems that describes the two lifestyles magically ("Farm Nights & "Cincinnati Nights").
