Book excerpt: At the beginning of the 1990s, Linda Grant's mother, Rose, was diagnosed with Dementia. In Remind Me Who I Am, Again Linda Grant tells the story of Rose's illness and tries to reconstruct the history of their Jewish immigrant family, stalking them from Russia and Poland to New York and London. Writing with humour and great tenderness, Grant explores profound questions about memory, autonomy and identity, and asks if we can ever really know our parents.
