It sounds like some hippy dippy leftwing book, interestingly enough, though the reviews could be misleading.
I don't remember the book being that way. It's a little bit idealistic, whatwith the little girl trying to make friends with the boy across the river, but it protrayed Israel as being in the right in keeping the land in the war of 1967.
