The O'Briens writes a fine balance between people and places, events; of carving and being carved (railway, family, war) so that its story is not plot driven any more than life itself can be. In this way it is similar to The Law of Dreams. Although one likes to believe experience and security bring control over life there are times for letting go and times for hanging on. The ending is particularly masterful as so much rested on how Behrens managed it. The O'Brien family tree grows strong and gnarled with deep roots and a crown of grace.
