"With her mega-bestseller Quiet, Susan Cain urged our society to cultivate space for the undervalued, indispensable introverts among us, thereby revealing an untapped power hidden in plain sight. Now, she employs the same mix of research, storytelling, and memoir to explore why we experience sorrow and longing, and the surprising lessons these states of mind teach us about creativity, compassion, leadership, spirituality, mortality and love. Bittersweetness is a tendency to states of longing, poignancy, and sorrow; an acute awareness of passing time; and a curiously piercing joy when beholding beauty. It recognizes that light and dark, birth and death-bitter and sweet-are forever paired. A song in a minor key, an elegiac poem, or even a touching television commercial all can bring us to this sublime, even holy, state of mind-and, ultimately, to greater kinship with our fellow humans.

Cain shows how a bittersweet state of mind is the quiet force that helps us transcend our personal and collective pain.
