Toronto Star, Aug 2016
I don't get paid by Liu Cixin or anything but I am crazy about his book, Three Body Problem. And in current news, his story is becoming even more plausible, as the origin for his alien race of Trisolarians is a planet orbiting Proxima Centauri, the same planet that has now been verified into existence. The Centauri star system is our closest Milky Way neighbor; it's four light years away.
