Experiments in gravity manipulation wake up a dormant race of robotic aliens around the solar system, with their main control unit buried deep below the lunar surface. In an instant the Earth disappears and the invaders begin to dismantle the planets to create a Dyson Sphere. Once I started reading The Ring of Charon I couldn’t put it down. This book is a perfect look at how far our technology can take us, and how dangerous technology can become. While machines attacking humanity isn’t a new concept in science fiction, this novel takes it to a new and epic level. ( )
