Sequel to This Is How It Ends

The world went to hell on Black Monday and, against all odds, Billy Gunn and Rory Wilder survived. But as the months drag on and gigantic alien ships arrive, new threats in the form of new alien species emerge. Holed up at Rory's grandparents' farm in the woods, they run out of food and supplies and are forced to make a trip into the city. The once-flooded landscape is now a frozen waste of mud and debris. It will be their last trip.

The alien ships are gigantic and defy explanation and understanding. They block the sun and leave the savaged earth shrouded in darkness. What do the aliens want? Why did the vast majority of the population die when they arrived? And why won't they stay dead?
