Having had the same experience as reading The Three Body Problem, I can safely say this is fast becoming one of my favourite series. 

The beginning can be a bit slow and takes a while to build but once you get settled in and used to the jargon this book becomes a masterpiece. Engaging, adventurous and reflective, it took me a few weeks to read the first third and then only two days to read the last two. There are many points in the book where I had to put it down and have a conference with my plushies over what I would do and say if I were in the characters' positions. The major plot points/twists don't seem forced or contrived but rather inevitable. Immediately starting the third in the series
