I loved the idea, I thought it was similar to Red Mars and Seveneves, that kind of hard sci-fi with political subplot. I really thought this book treated me as a reader with respect, subverting some of the assumptions I tend to make after having read a good number of science fiction. I thought it was a fresh take that had me racing to read the book at a fast enough pace to keep up with my imagination. The last third of the book got a little heavy on the politics end and I'm not sure the ending itself was my favorite. If it weren't for those things, this would be one of my favorite books.
