Seconding Three Body Problem for interesting setting/plot/actual fictional science.
It will subvert your expectations more often than not if you've gotten tired of modern scifi tropes. It takes a lot of time to chew on what the ramifications of certain events would be to society, and it manages to include one of my favorite mystery plots in all of literature.
Some people dislike the really hypothetical scifi elements but imho they serve an important and interesting narrative role. They're responsible for creating the unique technological climate in the books.
It's not for everyone, but if that sounds good then by all means I recommend it. It's a totally unique setting and style compared to western scifi that asks and tries to answer some very compelling questions.
