Amy Hall was wild, wilful and stubborn - struggling to make a success of the haulage business her dead husband Llew had created - and to come to terms with the shocking secret of his past.

Ralph Porter was handsome, successful and ruthless - "the richest man in Hillsbridge". He was waiting, it seemed, for Amy to make one slip that would enable him to absorb her struggling business into his own empire.

Beneath the Black Mountains in the small Somerset mining town of Hillsbridge, Amy Hall battles to find her very own Emerald Valley.
