Robopocalypse by Daniel H. Wilson
It is the not so distant future. Robots have become a typical part of everyday life; running errands, and taking over simple tasks. Cars are driven for you and toys interact with your children. The robotic presence is everywhere and welcome. That is until one computerized mind is created which can reason for itself and decides that the age of the robot has begun.
Yes, this book is science fiction, but it is also adventure tinged with horror. I just saw the movie Battle: Los Angeles and it was as action packed as that film. In the book you follow five or six groups of people from around the world (New York City, London, Kabul) and see the New War from their perspectives. There are a lot of great twists and turns that make this more than the average the world is ending book. Like learning that in a way the robots are environmentalists! Who knew?
The movie rights were purchased before this book was even printed, so make sure you read this one before it appears on the silver screen!
