Tara Selter is no longer alone.

Tara Selter has lived the eighteenth of November 1,143 times when she notices a break in the pattern: a man has changed his shirt. The man is Henry Dale, and he remembers all the days that have come before. He knows that time has fallen out of joint. Now they are two of a kind - trapped in the eighteenth of November, but no longer alone.

Together they learn to share their present; their voices grow hoarse recounting their small battles against it and their bewilderment at the disintegrating world. Henry sees things differently to Tara: he does not think that time will put itself back together and he does not think that the future will come around. But he makes her realise that she is no longer the same person she was before this fault in time. And he makes her believe that there may be others to find within it.

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