When Siddalee Walker, oldest daughter of Vivi Abbott Walker, Ya-Ya extraordinaire, is interviewed in the New York Times about a hit play she's directed, her mother gets described as a "tap-dancing child abuser." Enraged, Vivi disowns Sidda. Devastated, Sidda begs forgiveness, and postpones her upcoming wedding.
All looks bleak until the Ya-Yas step in and convince Vivi to send Sidda a scrapbook of their girlhood mementos, called "Divine Secrets of the Ya-Ya Sisterhood." As Sidda struggles to analyze her mother, she comes face to face with the tangled beauty of imperfect love, and the fact that forgiveness, more than understanding, is often what the heart longs for.
