A 10-year-old girl accidentally discovers the existence of a sister who died two years before she was born. That girl was Annie Ernaux, recipient of the Nobel Prize in Literature in 2022. Suddenly, Annie was no longer an only child, but the substitute for a profound absence that lives on in her parents’ unspoken sorrow. Her sister had to die so that she could live as the “replacement”. A delicate piece about guilt, family, and loss.
