I get some of the best books from Australia, and this is another one.  Machine Wars is about machines with artificial intelligence warring against humans.  The head machine goes rogue and begins warfare with its creator.  This robot, called Ahriman, thinks for itself, builds actual destructive weapons and is able to learn as it makes mistakes.  He builds soldier robots, drones, is able to hack into computer systems to locate people and to transmit misleading information, such as putting out APB’s on its creators family members and friends.  Its goal is to control the world and projects its persona onto a hologram in order to control people.  The concept is new and refreshing.  Apparently you’d have to be a total genius to understand how A.I. works, so the author doesn’t bother to explain; you just have to accept that it does what he says it does.  The story does start to drag a bit after the main character, Bram, and his friend, Stella, have to continually keep running to keep safe from Ahriman.  Their job is to keep Ahriman distracted while  Bram’s mother, the genius creator of Ahriman, finds a way to disable him.  A great adventurous, exciting read.
