The year is 1850, and Susannah Charlesworth loves the estate and open air life of the North Lincolnshire Wolds. She stands to become a very rich woman too - inheriting the estate, as well as her father's and uncle's wealth one day. But then she meets the dashing Daniel Bullen and Susannah's life is about to change forever.
As the eldest son, Daniel will take over his father's mill. He sees it as providing for a lifestyle he wants to pursue, but in order to avoid jeopardising the fortune that awaits him, Daniel must be careful how he conducts himself . . . and a marriage to Susannah will ensure that he becomes a very rich man indeed.
Whilst their marriage, and the children Susannah bears, ensures that their union is a happy one at first, Susannah soon begins to realise that there is more to Daniel Bullen than she thought - and that she hasn't married the man of her dreams. When Susannah's father dies, Daniel learns that the huge wealth that he thought he would amass has gone to Susannah's uncle. The fragile bonds between them are broken.
