The earth has been ruined; plague is rife and people huddle behind city walls, underground or in remote villages. There are no animals, no birds - and no freedom. And the divide between rich and poor is growing ever greater. Into this world comes Chevalier, an unassuming tax inspector by day but a secret law-breaker and risk-taker by night who decides to experiment with a new virtual reality headset - CIRCE. Suddenly, Chevalier finds he can dip in and out of a world long ago and far away where his deepest hopes and fears are met, where there's magic in the air, and where his spirit and bravery can emerge. With a collection of gods, goddesses, heroes and heroines both ancient and modern, Chevalier takes on the spirit of the legendary Gawayn; only as Gawayn in the virtual world can he save the devastated real world.
