This delightfully witty 1920s novel sees four dissatisfied London women escape rainy life for a sunny Italian castle, finding personal rejuvenation. The seemingly timid Lotty Wilkins recruits pious Rose Arbuthnot, socially exhausted Lady Caroline Dester, and stuffy spinster Mrs. Fisher to share an affordable rental for a month. Amidst wisteria and sunshine, they shed inhibitions, forming friendships that lead to emotional growth and rekindled, healthier relationships with their lives and partners.
