Following on from the climax of The Road Worrier, retrogamer Phil Grundy, his goth daughter Charlotte, the enigmatic Bryonetta Bootlesquith, Doc Nectarine and Sam Cooper escape the grip of the self-proclaimed ruler of Romford, Viktor Wendig, and the Assembly of Newly Uplifted Systems. Joined by two mysterious 'dragon hunters', the Ambivalence crew get caught up in a game of cat and mouse across the dystopian town, but as multiple instances of the ancient Entelechus Hex are invoked, the walls between reality and imagination start to crumble.

As they navigate the increasingly chaotic world, alliances are tested and fashion choices questioned. Will they defeat Wendig, or will it be enough to just get home alive? Will the dragon hunters find any? And why does Dexy suddenly seem to be just another ZX81?
