This story follows Kady and Ezra through a dossier like formatting which includes interviews, instant messaging records, emails, journal entries, schematics, images...etc. The story focuses upon the relationship between Kady and Ezra that just happened to end on the morning that their planet is invaded. When rescued, they are placed on separate ships and have to communicate through email or im, which means that they both end up withholding a variety of secrets from the other. Everything is all good until about 6 months after the attack when strange things start occurring with the AI and from there is where the story begins to take off. 
 I am torn between giving this a 3.5 or a 4 mostly because this book took so damn long to get into. I became invested in the story around the 200 page mark which should not happen in a book that is 599 pages long. It took a third of the book to get me interested in continuing the story. I found myself frustrated in the beginning because I could not get my bearings about what I was supposed to care about in the novel. Early on the two main characters of Kady and Ezra drove me slightly crazy. Also, every single swear word in this book is censored, which meant every time I came upon one I had to stop and pause and try to find the right words to put it into context. 
 The AI was the main reason I could not put this book down. There is some very nice prose bordering on poetry provided which lead to some very chilling lines. I am a sucker for interesting AI so this pulled me right in and from that point on I had to finish the book. 
 I was not super invested in the characters. Kady wasn't particularly likeable and I feel like if the journal entries were not included, I would not have really cared about her. Ezra seemed flat, but as a reader, we did not get a lot of information about his personal understanding of what was going on. AIDAN is what made this story for me because he was so complex in his understanding of his place in the world, but also his purpose. I could continue to gush about his characterization for a very long time, but it would probably include spoilers. 
 The pacing of this book was probably the most problematic aspect of this book. It is very slow in the beginning even though the characters were narrating about the destruction of their planet and, essentially, their whole entire lives. I did not care about the relationship between Kady and Ezra which is probably why it took me so long to get through the early parts of this book. 
 Overall, I enjoyed this story, but it took so long to get into. I think that I will end up rating this a 3.5 because of that. I will be checking out the sequel to this when it comes out because I want to know more about the politics and societies within the world of this book.
