"Caught up in character affairs instead of science."
I prefer hard SF and speculative fiction. This book provides an enjoyable amount of technical detail but I felt that the main discovery seems to have been delivered flatly and in a rush with too much attention paid to character driven action and affairs.
"Surprising and Unexpected"
I was quite surprised at how things developed in this book, especially around the overlords look. I was given something unexpected to think about and was quite grateful for that. A great book.
"Very Satisfying Book"
I love the concept and I love the story. I would have enjoyed it even more if there was more emphasis on speculative science and technology.
"Interesting Story"
I really like the main concept behind the book, but wasn't too sure if the Earth-side affairs were as interesting as I hoped they would be.
