The Darkness Outside Us

I read this books months ago and I still can't stop thinking about it. I'm usually good at guessing where a plot is going. Not this one. It caught me off guard time and time again in the best ways. I won't say too much so you can be surprised as well, but read on if you like sketchy AIs, secret conspiracies, and two boys who aren't quite enemies becoming a lot more than friends.
