Syn-En

A universe on the brink of peace. A defeated enemy out for revenge. And a weapon designed to destroy everything. Admiral Beijing York and his army of Synthetically-Enhanced Humans were built for war, taught to kill, and programmed to overcome all obstacles. Now, their final mission will take them to the one place no soldier is trained to go: Home. Turning her back on the NeoSentient Alliance, Nell Stafford tracks the origins of the new threat to Earth and an ancient race determined to unleash its deadly fury. Nell, her husband Bei, and his cyborg army will fight with everything they have. But this time, they're fighting an enemy with nothing to lose.
