After the battle against The 12, Amy and her friends have gone in different directions. Peter has joined the settlement at Kerrville, Texas, and has ascended in its ranks despite his ambivalence about its ideals. Alicia has ventured into enemy territory, half-mad, on the hunt for the viral called Zero, who speaks to her in dreams. And Amy has vanished without a trace. With The 12 destroyed, the citizens of Kerrville are moving on with life. But the gates of Kerrville will soon shudder with the greatest threat humanity has ever faced.
