This is an interesting but, but it didn’t seem on a par with other Hugo winners that I’ve read.
I found the story creative and pretty well told. I had some trouble with all the Chinese names but the list at the beginning of the book really helps.
It’s difficult to describe adequately without giving spoilers, so it has a first-contact with an unusual culture in an odd manner that leads to an invasion of the earth. And that’s misleading.
This is the first book of a tetralogy and ends on a down note.
