While I Was Away by Waka T Brown is a memoir of the author, who was raised in Kansas and had only visited her parents' homeland of Japan for short periods of time. At age 12, her parents sent her to Japan for five months to study in a regular elementary school and live with her maternal grandmother.
I recommend this to any child whose families send them away from their familiar surroundings to another country to bond with relatives or learn a language. In fact, even adult college students going for study abroad programs should read this. In my experience in study abroad programs, a surprising number of students don't perform well because of homesickness and failing to deal properly with the difficult and embarrassing situations Waka encountered.
