Oh my god I'm so glad this slog of a read is over. 

I feel as if there was often no room left for a reader's interpretation. Society and certain scientific tools were overly explained, making me have to skim read certain parts to be able to make it to the end. I'd rather just use my imagination to fill in the gaps.

There were also multiple moments in the book where possible potholes were explained via an awkward dialogue between characters. It made me feel as if the author was trying to impress me with how smart they were. Much was written as if it was an unlikable science teacher explaining to you that whatever scientific theories they taught you was the absolute truth and you were just expected to be impressed.

I found it hard to identify with some of the characters reasoning to do some drastic actions, but that's just personal so that's fine to me. I am surprised that no human figured out Luo Ji's plan. It was oddly simple even for someone without a background in the related fields.

The misogyny felt icky but could be explained away with "oh this is just how the main character thinks", but I would've liked to see more strong female characters.

I am again impressed by seemingly very unrelated scientific concepts being blended together into one fictional story. It was just much slower and longer than the story deserves.

I'm fine just stopping the series after this book and not bothering with the third.

I'm going to be thinking about this book for a long time. The first book felt oddly removed emotionally, like all the emotions were heard through a wall, but this book didn't have any of that, and I don't really know why they are different in that respect. Usually, overly technical science descriptions are a turnoff for me, but this again didn't have that problem, I actually feel like i learned a lot about our solar system. 
This book scratches the itch that older sci-fi books have, of a mythic scale and dramatic, eerie scenes that speak on the human condition. Any sci-fi fans should give this series a read, you won't regret it. 

I didn’t like it as much as The Three Body Problem but it was still very good. After TTBP I was very eager to get straight into this book. Now I’m taking a break before reading the third. But I will!

Super slow at the beginning, but what a superb finish.

My complicated relationship with this series continues. So much about this one is brilliant, but it is absolutely buried in things that made me so frustrated.

Too many times did characters suddenly have a nose dive in intellect so that the science can happen, when the science in question is so far beyond what they were capable of any way that it didn't need them to spend 10 mins scratching their heads. The human element was so weirdly clinical and inconsistent, but half of them spoke like they were all vying to get the perfect soundbite. Plus it added pages just to explore the human element but somehow still managed not to add much depth to any character other than Luo Ji. It's bizarre how many pages were devoted to this and I still barely know any of them.

I loved the actual plot and I think so many of the ideas were beyond creative, but it was just brought down by the weird need to 'but wait there's more!' its way to the next section. 

This book was such an excellent continuation from the first installment! I felt like the was a plot twist on every other page. This book really stands apart from other sci-fi stories, because it allows us to capture a complex and ever-changing view of humanity. At times throughout this story, I had a strong disdain for humanity's weaknesses, and other times I was reminded that our unique strengths make us so powerful when we are united. Overall, I loved the book, and I can't wait to read the final installment in the series.
