In a lonely house deep in the Black Mountains of south Wales, a man spends insomniac nights absorbed in the ancient texts left him by his mysterious aunt. When a blue tent appears in the field at the end of his garden, his solitary life is turned inside out. But who owns the tent? And when the tent's occupants emerge, whose story are they telling? As his life unravels, the man begins to question whether he is the orchestrator or the victim of his own experiences. Are the stories that guide or steer his life – any life – real, or merely the echo of other, possible lives?
