I'm currently about two thirds of the way through The Three-Body Problem that I got as a gift for Christmas and I'm really enjoying it.

It's this mad, sometimes quite complex, but very entertaining Chinese sci-fi novel. It manages to heavily incorporate a lot of elements I know almost nothing about (namely physics and the Chinese Cultural Revolution) into proceedings but still remain very readable. They did a really good job on the translation of adding appendix notes throughout at the bottom of the pages to give context to a lot of the Chinese references they make and the more complex scientific concepts they bring up.
