Plot A time loop drives the story. In Solvej Balle's interpretation of the time loop trope, Tara Selter, a dealer in rare and antique books, keeps repeating a single day, November 18, except that Tara's starting location for each day is not fixed. Rather, she begins each new day wherever she ended the previous day. This gives her far more freedom than other time loop protagonists, including those found in the 1993 film Groundhog Day or the 2020 film Palm Springs.
In volume I, Tara describes how she first began looping during a trip to Paris and she details the days since she returned to her home in rural France, where she lives with her husband Thomas. Only Tara retains a memory of the previous November 18ths, and she has to start every day by convincing her husband of what is happening to her. Meanwhile, her body and some material objects continue to move through time. An injury she received in Paris slowly heals, groceries vanish overnight, and her handwritten notes do not.
In volume II, Tara uses her freedom to travel throughout Europe, visiting different climates in an attempt to experience the seasons. She meets another person who is also experiencing a time loop.
In volume III, Tara becomes increasingly concerned about the consumption of resources, and the story becomes "a parable about humanity's abusive relationship with the natural world".
Critical reception This book has received positive reviews:
In The New York Times, Hilary Leichter wrote: "Here, the time-loop narrative takes on new and stunning proportions. Whereas the reader expects the loop to be straightened by sheer will or gamed through kindness, Balle dismisses such resolutions for something much more compelling. 'I no longer believe that I will suddenly wake up to a time that has returned to normal,' ... Tara Selter, thinks."
Jake Casella Brookins wrote in Locus magazine: "Balle's combination of narrator and setup is quietly genius. On the Calculation of Volume is not about comic repetition in the style of Groundhog Day, more in tune with the uncertainty and uncanniness of something like Russian Doll.... Balle has nailed – and Haveland has ably translated – a remarkably believable, organic voice, a kind of quotidian existential mode that is equally suited to evocative descriptions of the world and to perceptive ruminations on the nature of time, relationships, and the self."
In The Atlantic, Rhian Sasseen wrote: "On the Calculation of Volume's premise could, in other hands, be reduced to a gimmick. But in Haveland's rendering, Balle's stripped-down prose has an understated clarity that lends philosophical resonance to this fantastical setup."
Morten Hoi Jensen wrote in The Washington Post that "Written in intermittent diary-like entries of varying length, On the Calculation of Volume is at once scrupulously realistic and intriguingly speculative. Balle succeeds in conveying the texture of Tara's changing feelings, her shifting moods. There are moments of crisis and accident interspersed with bursts of enthusiasm and even, at times, hope."
