How do I begin? 
 This novel, while an investment at 861 pages, was a new experience of sorts for me and an enjoyable one at that. I had to look up the term "hard science fiction", which is what some have categorized this book as being and is a sci-fi category with lots of technical detail and an aim at scientific accuracy. I'd agree with that. 
 Seveneves is split into three sections with the first two very heavy in technical and scientific speak. While I can't admit to understanding all of it, I did make a point of being very alert and present while reading and trying to visualize what Stephenson was explaining. In other words, if you want text that's just going to hit the highlights and be a breeze to get through, this is not your book. I did, however, feel that all of the extended explanation added to the "gravity" (no pun intended) of the story. 
 I will admit that when the story got around to the morsels of human interaction, I was grateful for the reprieve and very invested in how things would turn out. At the apex of the second section of the book, we are swiftly tossed into the third section, which takes place 5000 years into the future. Though this section was lighter on the technical jargon, it was my least favorite part. I wasn't as invested in what was to come, because so much had already been and gone that I missed out on. Stephenson does attempt to cover some history here, but it falls a bit flat and doesn't give nearly enough. I feel like the third section could have been fleshed out into a sequel, perhaps. The book also has a rather incomplete and uneven ending, though not an unsatisfactory one. 
 That being said, I enjoyed most of the book and am glad to have gotten through it. It feels like a minor achievement on my part! Thank you William Morrow and Goodreads for my book which I received as a Giveaway!
