What is it to be oneself, and what is it to lose one's self. Who are we when we are not ourselves, and where do we go? This is a book about dementia - not a personal account, but an exploration, structured around this radically-slowed death. Full of people's stories, both sad and optimistic, it is a journey into the dusk and then the darkness - and then out on to the other side, where, once someone is dead, a life can be seen whole again.
