In "The Memory Keeper's Daughter" by Kim Edwards, the protagonist experiences a profound sense of sadness that lingers beneath the surface of a lively social setting. This sadness becomes a weight she carries, symbolized by the imagery of a dark stone in her hand, representing her inner turmoil and emotional struggles.

This encapsulation of her feelings highlights how individuals can often mask their true emotions in public, while privately wrestling with deep-seated pain. The contrast between the vibrant atmosphere of the party and her internal sorrow emphasizes the theme of unexpressed grief and the burden of memories that shape one's identity.
