The Enemy uses a primordial curse coupled with a cosmic plot to vector a wretched disease into modern humanity. He who dwells in the secret place of the Most High shall not fear the terror by night, nor of the pestilence that walks in darkness. But those that do evil welcome the darkness. For their wicked deeds are exposed by the light. And some seek to cast the whole world into darkness. Nadia Roman has found a way to blot out the sun. So that her kind may thrive in the twilight. If she has her way they will breed and hunt. Through seemingly serendipitous circumstance the librarian, Gary Landau, and his daughter, Cortney, are cast into the breach between darkness and light. Our planet spins at the brink of catastrophe. If Nadia has her way mankind will become...well...cattle.
