Robopocalypse

It's told as a series of reports on events that led up to the conclusion of a great fight between humans and robots. You kind of have to remember these as a person described in chapter 3 might show up in important ways in chapter 15.
It was a little irritating that, after telling the story of that chapter, the narrator would comment that, later, this event would lead to this person saving all mankind or something.
Some of the stories, especially the airplane story, were quite terrifying.
All in all, I thought it was well thought out and there were several surprising twists.
