This historical fiction novel follows Guinness heiresses Aileen, Maureen, and Oonagh, as well as their companion-of-sorts Kathleen, through the 1930s - from the stock market crash to the precipice of the Spanish civil war and World War II. Their marriages, affairs, divorces, and decadent lifestyle and parties are set against a backdrop of political unrest and social change in Europe - brought partially into focus by Kathleen, who straddles both worlds. It was very interesting especially with the multi-POV. This is technically a sequel to The Glorious Guinness Girls but I read it standalone and you totally could too!
