One bridgehead. Four lives. Zero margin for error.

Lieutenant Grant Richardson's mission is simple: blast through enemy fire and take the Volga Bridgehead. Failure means certain death—and the collapse of the entire front.

Nearby, his brother Zach leads the last tank platoon holding the line. One wrong move, and the Russians will force the Americans back across the Volga.

In Washington, their mother—US Secretary of Defense Gina Richardson—is fighting a different war. The enemy is the President himself, and he may cost her the chance to save her sons . . . and her country.

Russian General Nikola Korolev knows this battle will decide everything. If the Americans win, Russia loses. He'll do whatever it takes to stop them—even if it means unleashing the unthinkable.

The fight for the bridgehead will decide the war. And maybe the world.
