When North Korea detonates a nuclear weapon at the edge of space, silencing dozens of satellites, rogue nations seize a unique opportunity to strike. An avalanche of crises erupt, fueled by a dearth of space situational awareness. Overnight, national leaders robbed of spy satellite imagery are making decisions in the blind. An Iranian missile threatens to destroy Israel; a Venezuelan "research" satellite jeopardizes the lives of three astronauts, and tech-savvy terrorist cells unleash back-to-back horrors in California. The White House turns to U.S. Strategic Command and its team of Deadsat II wargamers, racing the clock to stave off international disaster. But power-hungry officials are undermining those attempts. With a B-2 bomber minutes from obliterating a Chinese laser-weapon site, and two U.S. aircraft carriers in China's missile crosshairs, two great nations stand at the brink of nuclear war.
