This second chapter of "The three body problem" is perhaps even better than the second. Cixin Liu really revealed to be a master of science fiction. The story in this volume starts few years after the first one. It is, however, quite different as the characters are for the majority new (thanks to the hibernation trick). Here the psychedelic atmosphere of the mysterious videogame are abandoned as well as the chinese historical roots of the plot. The first part mainly focused on politics while here we get into more classic science fiction. The story proceeds smoothly, never boring, without those jumps in the plots that made the narration a bit more difficult to follow.
The end is a bit hurried but surprising. I have great expectations for the sequel.
