Each chapter helps us navigate an issue that define our lives, from love to death and from authenticity to creativity. Using examples ranging from music and cinema to parenting and business, as well as her own life and the latest academic research, she shows how understanding bittersweetness will allow us, in a flawed world, to accept the loss of past identities; to fully embrace the loves we have; and to weather life's transitions.

Bittersweet reveals that vulnerability and even melancholy can be strengths, and that embracing our inevitable losses makes us more human and more whole. This is a book for those who have felt a piercing joy at the beauty of the world; who react intensely to art and nature; and in a culture that celebrates toughness, who yearn for a wiser and more meaningful world. For bittersweetness is the hidden source of our love stories, moonshots and masterpieces.
