In the 18th century five men created the biggest industrial city civilization had ever seen. They were the Iron Masters, masters of metal and men. Their cannons saved a kingdom, forged the greatest empire in the world and changed the history of the human race. Intrigue, bribery, adultery, and murder were common in Merthyr Tydfil, a town where the furnaces burned day and night, the sun seldom pierced the soot-filled sky, and the Iron Masters ruled without pity.

Nye Vaughn, a humble farm boy, walked to Merthyr to find his destiny, unaware that a war was coming which would engulf the known world and make bold men rich. To fight Bonaparte, Britain needed cannons, thousands of them. Vaughn built the largest foundry of them all and made his fortune but, when the world changed, the iron behemoth he constructed turned on him.

Graham Watkins joins the ranks of historical authors as he weaves fiction and fact together with a pace that makes the listener keep listening. The Iron Masters is a story of family, greed, betrayal and war. It's scope is epic from Wales, to Baltimore, from the age of sail to steam railways, from the Battle of Trafalgar to the defiant raising of the American flag over Fort McHenry, signalling the confidence of a new, powerful nation. Many of the characters and events are true and reveal an amazing time in our history.
