Honor Guinness is rich, aristocratic, shy and awkward -- nothing like her glamorous cousins Aileen, Maureen and Oonagh.

But when she marries the charming and ambitious, American Henry 'Chips' Channon, together, they make the perfect couple. Determined to conquer London society, they are soon are at the heart of the best social circles -- including a close friendship with the Prince of Wales and Mrs Wallis Simpson.

But within the marriage, all is less than perfect.

Meanwhile, Honor's best friend, the beautiful, enigmatic Doris, is focussed on marrying well to provide security to her family. Born to a German-Jewish mother, she has charm and looks but not Honor's advantages of birth and connection.

Set 1932-1936, The Other Guinness Girl is an evocative story of excess and wealth against a backdrop of events that changed Europe: The rise of Nazism, the abdication of a king, and the slide into World War II.

But will Honor, and Doris, find where they belong in times of change?
