"The needs of the many outweigh the needs of the few - or the one."
Ken Liu has done it again. This story should win awards this year. Here, Liu explores the Japanese cultural concept of acceptance of the transience of all things, in the face of an Earth facing imminent destruction from a rogue asteroid - and characters who make the decisions they believe to be right. I'm not usually a big proponent of self-sacrifice, but the examples in this story make a good case. Emotionally wrenching, and beautiful.
