I just want to start off by saying that this book did more right than it did wrong, but unfortunately, what it did wrong happened to be the writing style, and it was hard to ignore. It was glaringly informal, from the sentence structure to the punctuation ( I don’t think I have ever read a book that had a sentence ending in ?! ), and came off as very cheesy, despite the impressive plot and research that went into the story. If it weren’t for how interesting the book was right off the bat, I don’t think I would have continued reading.  I was drawn to the concept initially, and the science was purely impressive.   I know nothing about physics or astronomy, and despite the in-depth scientific explanations, I was never lost. That alone takes skill, and the pacing of the story was also skillful. I truly raced through this book and for that alone, I think it deserves a high rating from me.
