Two very different sisters - well three, but one doesn't get much of a look in - take paths through the world which are not at all the ones their parents expect. I couldn't really believe the relationships upon which the older two chose to embark, although their reasons were sympathetically described and fairly tragically-credible. The novel was a little tale of a slice of growing up: that bit where siblings turn into people in their own right, their lives suddenly become more of a mystery and their reactions can no longer be predicted. So some big ideas explored but still, somehow, slight.
