Four very different women, all wanting to escape cold and dreary London for different reasons, come together to share a month& apos; s holiday in an Italian medieval castle. There's timid Lotty Wilkins, terrified of her domineering husband; sober and religious Rose Arbuthnot; rigid and judgemental Mrs Fisher; and the breathtakingly beautiful but disillusioned and unhappy Lady Caroline Dester. They are lured to the castle by the advertised & apos; wisteria and sunshine& apos; , but they end up finding there so much more than they had bargained for. The place transforms them and their lives are unexpectedly changed. Von Arnim& apos; s story of their metamorphosis under the Italian sun is warm, witty, intelligent, and as enchanting as the title suggests.
