The Three-Body Problem 3: Death's End

In Death's End, the author employs his imagination and scientific knowledge to explore the very nature of the universe—pure hard sci-fi.
This series features a lot of talk about dimensions.
I tried to visualize everything at first, but eventually, I gave up trying to imagine it all.

The same human greed and arrogance seen in the second book reappears in this one.

I really didn't like the female protagonist. She's too idealistic and naive.
She couldn't distinguish between ideals and reality, and the consequences were disastrous.
Personally, I felt the story could have ended with The Dark Forest.
However, I suppose this volume was necessary for a truly complete conclusion.
