The first half of this book is not so wonderful. 
 I got this book expected a sci-fi about sentient machines, not a romance novel that happens to have some sci-fi things in the background. A couple of things are mentioned about the AI Charlotte, but hardly enough to really even merit being mentioned in the synopsis. EVERYTHING is all about Nico and Lee, and Lee fawning over Nico. This book made me look up things like "Are coconuts native to Chile" because of the sheer amount of times Lee mentions that Nico, who is from Chile (more on that later) smells like coconuts. Regardless of how odd that detail is, I still have no idea if it's even true. Not exactly the most pressing issue though. I do appreciate the diversity of having a gay main character, but that was really not close to enough to make me like the book. The characters themselves are not bad, although none really stood out to me. If I had to pick a favorite it would be Bex, the indignant feminist journalist-in-trainging at a time when the US is going backwards in terms of equality. 
 The second half is far better. 
 It finally turns into the sci-fi book I was expecting. AI attacks! Betrayals! Finally! Although I did guess the big plot twist early on in the book (view spoiler)[ Nico is an AI himself, so not technically from Chile (hide spoiler)], the latter half of the story was far more exciting. There are a few interesting and well written parts regarding the Ai's, especially one involving an old video of Charlotte. In it, Charlotte and her creators are playing cards, and although Charlotte seems human in almost every way, she grows frustrated as she can't pick up on non-verbal clues people are giving as she is a robot. Charlotte actually makes an appearance at the school, and Lee tries to find a way to stop her along with finding out what exactly is up with the dean of the school. 
 If you want an easy to read contemporary novel, the first half of this book is for you. If you want a sic-fi action story, the second half is for you. If you want to read the whole book... 
 The story as a whole is pretty easy to read, and not very-thought provoking, so I wouldn't worry about getting nightmares or being morally disconcerted after reading this book.
