The United States, China, and Russia eye each other across a twenty-first century version of the Cold War, which suddenly heats up at sea, on land, in the air, in outer space, and in cyberspace. The fighting involves everything from stealthy robotic-drone strikes to old warships from the navy's "ghost fleet." Fighter pilots unleash a Pearl Harbor-style attack; American veterans become low-tech insurgents; teenage hackers battle in digital playgrounds; Silicon Valley billionaires mobilize for cyber-war; and a serial killer carries out her own vendetta. Ultimately, victory will depend on blending the lessons of the past with the weapons of the future.
