I think this is a book every child in the United States should read. I loved it! There's so much kindness and gratitude in it as well as a great realization about how others live outside of the U.S. To clarify some of the comments in the kid reviews…. I'm just going from memory of when I read the book about 9 months ago, but Caitlin (one of the primary characters) starts out in 7th grade and the book continues for several years. She writes about her personal life and she does mention developing breasts, but it is brief. She does not at all, in my opinion, go “on and on” about her “bodily developments”. When Caitlin gets older there were a few references to partying and drinking but these were pretty mild and brief, and just help to illustrate the differences between the concerns and daily lives of 2 teenagers who live in different parts of the world.....…. This is a sweet, happy story with so many good messages! Great for anyone grade 7 or above.
