Edinburgh, 1822: A poignant love story and coming-of-age tale. Kate Dunbar and Richard Hope come from very different worlds. She works in an oyster cellar within the gloomy vaults of the South Bridge. He’s a wealthy medical student. Can the rigid class structure of their time allow them anything more than one sweet moment of happiness? One Sweet Moment is set against the richly-evoked historical background of King George IV’s visit to Edinburgh in 1822 and the Great Fire of Edinburgh of 1824.
