The Uncoded Reply

It began with a six-mile shadow. It ended with a countdown to silence. Dr. Kate Lin, a civilian data scientist, has the only intelligence that matters: the Uncoded Reply, a defense protocol stolen mere hours before the global invasion. Her frantic escape is a tightrope walk of pure terror not because of the alien fleet, but because Agent Marcus Wells, an elite military operative, is closing fast. Wells has orders to seize the data and terminate the source. When the massive Exodus Ark delivers its first, devastating strike, the global military structure collapses. Wells's mission warps into something more savage: he becomes a ghost in the ruins, hunting Kate through the shattered remnants of civilization. But the aliens are not making war; they are performing an execution. To manufacture the one weapon that can reach the Ark, Kate and Wells are forced into a hostile, high-tension alliance that threatens to kill them both. Their expertise is lethal, their mistrust absolute, and their target is beyond comprehension. They have one final, desperate window to fuse Kate's code with Wells's resources and deliver a weapon that must pierce the enemy's terrifying technological supremacy. Failure means the total, organized extermination of the human race.
