Warning: wikipedia contains spoilers The novel tells the story of the Morgans, a poor but respectable mining family of the South Wales valleys, through the eyes of the youngest son, Huw Morgan, whose academic ability sets him apart from his elder brothers and enables him to consider a future away from this troubled industrial environment. His four brothers and his father are miners; after the eldest brother, Ifor, is killed in an industrial accident, Huw moves in with his sister-in-law, Bronwen, with whom he is secretly in love. Later, his father is also killed in the mine. Meanwhile, Huw's only sister, Angharad, catches the eye of a wealthy coal-owner, but the marriage is an unhappy one and she enters into a clandestine relationship with the local minister. The death of Huw's father, coupled with the realisation that Bronwen has no romantic interest in him, causes him to leave the valley. In the sequels to the novel, Huw emigrates and makes a new life in Patagonia.
