A nuclear device detonates high above the North Atlantic. No city is destroyed, and no government claims responsibility. Yet satellites disappear, power grids fail, and communications collapse, leaving commanders to interpret a crisis they can barely see.

In Washington, Moscow, Beijing, Jerusalem, and Europe, leaders search for answers while military forces prepare for the worst. Submarines move into position. Missile crews wait for orders. Intelligence agencies struggle to identify an enemy before an assumption becomes an irreversible response. Continuing the Day Zero saga, The Chain of Decisions follows a world in which the loss of information can be as dangerous as the attack itself—and both hesitation and haste carry a price.
