Death's End by Cixin Liu

​This thrilling conclusion is actually amazing with very many plot twists, new stories, and creative explosions of ideas that accelerate until the end.  Each time you think you have it figured it out there is another twist.  You must slog through the (terrible!) first book to get to the (decent) second book to reach this (awesome!) third one.  I speculate the Chinese original is better. 4/5 stars, recommended.
