On the Calculation of Volume I: Shortlisted for the International Booker Prize 2025

Every morning, she wakes up to the 18th of November. She no longer expects to wake up to the 19th of November, and she no longer remembers the 17th of November as if it were yesterday. She comes to know the shape of the day like the back of her hand – the grey morning light in her Paris hotel; the moment a blackbird breaks into song; her husband’s surprise at seeing her return home unannounced. But for everyone around her, this day is lived for the first and only time. They do not remember the other 18ths of November, and they do not believe her when she tries to explain. As Tara approaches her 365th 18th of November, she can’t shake the feeling that somewhere underneath the surface of this day, there’s a way to escape.

Shortlisted for the International Booker Prize and Winner of the Nordic Council Prize for Literature, On the Calculation of Volume I is the first volume of the poetic, page-turning European masterpiece about one woman’s fall through the cracks of time.
