At first, it was a little slow, but once everything gets going, it’s the kind of book that it’s hard to put down because you want to see what happens next. For me I couldn’t really anticipate what happens next. The book definitely kept me in suspense. If you like science-fiction dramas/thrillers you’ll love blue shift. The only part of the story that I found tedious was the Martian aspect it definitely left me wanting more. otherwise everything that happened on planet earth was awesome.
