“Mum” is part literary detective story, part personal journey. Julia Creet's mother, Magda let go of her Jewish heritage and converted to Christianity after immigrating to Canada. She tried desperately to forget the horrors of the Holocaust and thought Christianity would protect her children. Creet delves into her mother's secret past, following a trail of clues: her mother's memoirs, letters and poems, a news article about a Hungarian grandfather and a cache of letters, poems and manuscripts he'd written in a language Creet couldn't understand. All of these led her to Hungary where local memory revealed the story her mother has tried to forget all these years.
