Illuminae - Jay Kristoff, Amie Kaufman 4.5 stars

This book is awesome. I didn't have it figured out at all. Everything was fresh for me. It's in the future. People are in space. It's the files of a tragedy and a sort of government or company cover-up. But this is the files of what really happened and fighting back. The AI aspect is so interesting also, the way that it becomes so human.
