THE SUNDAY TIMES BESTSELLER and A BBC RADIO 4 BOOK OF THE WEEK . . . 'Somebody I Used to Know' gets to the very heart of what it means to be human. What do you lose when you lose your memories? What do you value when this loss reframes how you've lived, and how you will live in the future? How do you conceive of love when you can no longer recognize those who are supposed to mean the most to you? It is both a heart-rending tribute to the woman Wendy Mitchell once was, and a brave affirmation of the woman dementia has seen her become.
