I suspect this story won't appeal to everyone, but I thought it did a great job of discussing the role of history in society. Set on a generational starship, the question arises as to the relevance of the history of Earth when the many generations in the future finally find and colonize a new planet. I'm not sure the story really adequately answers the question, but it does make the reader think, which is the hallmark of a good story. I can understand the perspective of the young people who were born on the ship and will never see anything but the ship. I was a surly teenager once, too. But I can also understand the perspective of the adults who don't want to lose their connections to their ancestors and history; those are a big part of what makes us human. The story didn't really give much middle ground, i.e., why can't you both preserve your history while making new memories? After all, that's what we do all the time now. Some things are forgotten so that new things can be created, but the major strokes of history are there to be studied and learned from.
