As I expected, I loved this book. The scope was so far beyond what I could have imagined, and though the tone was sadder than I anticipated coming from the first two, I found it very fitting. Liu has crafted a very plausible feeling explanation of what may be outside our Solar System, in the greater Universe we know so little about. The vastness of it all is incredible to comprehend. For me, the character of Cheng Xin was in many ways a highlight of the story, and I delighted in relating to her in her growth, struggles, triumphs and pain.
