With passion, humour and remarkable insight Gwyn Thomas captures the world of South Wales in the 1830s during the turbulent years of the Merthyr and Newport Risings. As the newly-built foundries enter their first decline, a travelling harpist from the rural north arrives in one of the new towns to find his friends caught in a fiercely-fought industrial dispute, a dispute which quickly spirals out of control. A powerful and sweeping novel by one of Wales's great literary figures, 'All Things Betray Thee', tells the epic story of a people, their joys and victories, but also their sorrows and defeats.
