Who will end humanity first, the aliens or us?!

'The Three-Body Problem' by Cixin Liu is a sci-fi novel involving aliens, science, warfare and politics. Unexplainable events start to occur to scientists after contact has been made with the Trisolaris world. We gradually learn about their unique ecosystem and why humanity might be in danger not just from the outside, but also within. I loved the first 2/3rds of the book for it's distinctive plot/style but was slightly disappointed at how rushed the end felt. Was still a great read overall though.
