This is a truly impressive SciFi book. At first, the threat of an alien invasion might seem like the same old story, this is a unique take from page one. Exploring the idea of a civilization in a chaotic three-sun system, it also ties in with exploration of Chinese society. And towards the end, it brings in some very impressive (imagined) physics idea. The big ideas, the Chinese perspective, and the even narration that moves just at the right speed and is itself full of ideas, are all making this very special.
