Walkaway culture makes for really cool reading because it begins with modern science. 3-D printing provides our heroes with everything they need. DIY enthusiasts build drones, zeppelins, and mecha from scratch. Scientific breakthroughs travel across the globe at a dizzying pace thanks to file sharing and open source technology. It boldly imagines a world without the need for government. The Walkaways accept all except the greedy and the oppressive. It calls to mind Robert A. Heinlein’s novels, but pressed by the left wing instead of the right.
