4.5/5 Stars 
 This book was so so so good! I didn't really have too many expectations going into it and I was mind blown by the end. I enjoyed the different format of the book because it makes the story feel even more real and intense. This book is a perfect binge read, and I highly recommend reading it as such. 
 Illuminae could have easily been a stand alone with a bit alternate ending, however, I look forward to the next book in this trilogy.
