Blackcollars. Allen Caine had never met any of those superbly trained guerrilla warriors, but their exploits in the war against the alien Ryqril invaders were legendary. Chemically augmented with drugs to prolong youth, double speed and reflexes, and enhance memory, they were a special task force trained in hand-to-hand combat against an enemy far more powerful and swift than human soldiers. An ultimate weapon more insidious than the giant Nova-class battle cruisers, the Blackcollars had been the deadliest men in the history of Earth warfare.
But that was 30 years ago - that war had been lost - and Allen Caine, an operative in Earth's underground Resistance had a mission to complete. A last-chance effort to overthrow the alien domination of Earth and her colonies would depend on his re-convening a Blackcollar unit - if they still existed, and if he could find them.
