From somewhere beyond our galaxy the great comet Lihtan appeared in the night sky, slanting down out of far cosmic spaces to enter the galactic plane. When it is seen to swerve onto a collision course with Earth, a tempestuous debate erupts among the world's punditry over whether physical evidence or paranormal suppositions should guide a terrified humanity into the imminent crisis.The rising commotion comes to nothing on the night of the near miss, when Lihtan brings to Earth a titanic atmospheric disturbance and massive cometary snowfall along a thousand-mile track up the west coast of North America. By the following morning, civilization in the region has ceased to exist. But there are survivors who, amid the devastation left by the storm and the weird after-effects that follow, find themselves inhabiting a world inexplicably changed.Six years after the comet.Doc had thought her battles with the revolting Uni invader were behind her. But now, Doc Holiday is asked to volunteer--yet again--to run battlefield rescue operations in the comet-affected zone, in defense of the feisty young 9th Amendment Republic.

And this latest Uni assault looks to be the most insidious of all. Plunged into a maniacal plot to hijack the alien physics at the core of her beleaguered Republic, Doc and a handful of allies go head-to-head against a mind-bending scheme that aims to stuff all of humanity into the putrid hind pocket of a power-crazed Uni elite.What trials await Doc Holiday in this unexpected confrontation? What of her crew, each with a story to tell and an unbidden talent brought to Earth by the comet six years before? And what is the terrible secret that burdens her chief ally? There are still questions unasked, threads yet to unravel in the mystery surrounding the comet and its effects. Above all, can Doc make real the power of the comet and use this to foil Unitory ambitions?.
