Anna Jacobs' new Lancashire saga tells the story of the last of the Kershaw sisters - the unexpected Mary Ann.

Anna Jacobs grew up in Lancashire and emigrated to Australia in 1973, but loves to return to England regularly to visit her family and soak up the history. She has two grown-up daughters and now lives with her husband in a spacious waterfront home. Often as she writes, dolphins frolic outside the window of her study. Inside, the house is crammed with thousands of books.
