I read this at the same time I read another book which was similar but different. I was ashamed to admit that I had trouble with some of the names, not the fact that some of them were the same, but not being able to determine nuances by what people called one another etc. I enjoyed but had a hard time with the hard science-y aspects of this book since I felt like there was a lot of telling-not-showing and ultimately it wasn’t about the human stories at all which were the parts I found most compelling.
