Death's End

This trilogy is like a detailed game of Civilization with a strong understanding of science and human nature, with Death's End being the end of the epic.

I really enjoyed the multiple generations and the different perspectives as time goes on. Liu continued to surprise me with the story, even when I thought the end had come. Some may find the scientific detail a drag, but I found it fascinating. I'm sure there are a number of speculations based on current understanding, but I found it stimulating and intriguing. This is the best quality science fiction I've read in quite some time.
