Holy cats. This book was unique. 
 I've always defended my love of fantasy, sci-fi, and post-apocalyptic novels by saying that these genres helped us parse out what it means to be human. And this book throws all of those genres in a blender and pours out a great big smoothie of humanity. 
 It took me a while to get used to the style; typically, I am not a fan of books that are told primarily through instant messages or anything of that ilk because they often feel dated by the time they are published. But it works here, and there is honestly no other way to tell this story. You get used to it, and even if it does take a bit of time, this crazy creative story is worth it. 
 That is also one of the reasons that I believe this book would never work as a movie. So much of it is just through emails and the magic of computers, and that sort of suspense and human emotion is difficult to convey to a screen. 
 I will definitely be snagging the sequel of this one as soon as I can. 
 (view spoiler)[ Also, can computers write poetry? I actually adored some of Aidan's little musings. It was one of those things that kind of fucked me up in this book-- it helped Aidan transform from the typical evil-AI-thinks-it-knows-better-than-humans-and-will-destroy-them-as-a-result into an actual being that I somewhat care for and whose motivations I understood.
