The eleventh book in the Star Patrol series tells the story of Krona and the events around the planet, engulfed in civil war. The commander of the Alkhon detachment Brod, being seriously wounded, is captured by the Void. The remnants of his unit are unable to leave Kron due to damage to the interstellar shuttle, but are forced to hide among the ravaged Kronenburg plain. The spaceport is completely captured by the Void. The mercenaries follow in the footsteps of the Alchonians, but are forced to divert their attention to Kronenburg, where the remnants of the loyalists and discredited peacekeepers from Terra Nova are settled.
