Many scientists believe that about every 200,000 years, a magnetic pole shift flips the axis of the earth, resulting in sudden and devastating climate change and planet-wide devastation. We are overdue. Five generations after the next 'Turning', the descendants of the few surviving humans carve out a medieval-like existence in the rubble of a ruined city of London. Meanwhile, the goblins live a shamanic, anarchic lifestyle and stay unseen by humans for their own survival. Until one day a human wanders into one of the forgotten underground stations where he is captured and drugged with a mushroom potion that causes memory loss, then expelled. A search party happens to see one of the goblins, and the humans try to dig out the 'demons'. A goblin woman is taken captive but escapes, and it is up to the leader of the humans, Count Anton, to find her and return her to her people.
