On the Calculation of Volume (Book I)

On the Calculation of Volume (Book I) by Solvej Balle

A rare-books dealer goes off to the city to attend a convention and buy some books. She runs into some friends and gets a burn moving a heater. Then she wakes up the next day and finds the newspapers are for the previous day. A diner at breakfast drops their bread in the same way. She discovers that she most continuously repeat November 18th. She decides to travel home and discuss it with her husband/business partner. While she seems has memories of all her previous experiences, no one else does. Her hair and nails grow. She also can take some things with her. Together they also find that the "reset" happens at some arbitrary time. Eventually, she decides to go away. Near the year anniversary, she attempts to return to the hotel she was staying and see if she can progress to a different day. She does things a little different and then discovers some new things. Does the day progress?

This is similar to the movie Groundhog Day. One person continuously relives the day. This one has a much more intellectual approach. (As would be expected from a book dealer vs. a news anchor.) She doesn't spend much time trying to make minute changes and optimize the situation. Instead, she focusses on figuring things out in the hopes that she can find out why.
