The author recounts the last months of her sister's life as she slowly died of breast cancer in her mid-20's. The narrator and her sister, Cyndy, renegotiate their relationship and family roles throughout the illness. The narrator addresses the issue of living despite the prospect of dying, and of trying not to die while in the midst of attempting to live one's life. The narrator also recognizes the centrality of desire (in its broadest sense) in our lives, and describes our guilt about satiating our desires, the sense of loss from not ever really satiating them, and the inability to satisfy the desires of another.
