"On the Calculation of Volume" by Solvej Balle
Fantastic book. I read it in one day. I don't think I've done that before.
It's a Danish book about a woman stuck in a time loop, like Groundhog Day, but with some notable differences. Like, if she buys things, she might still have them the next time she wakes up.
It's a seven-book series. Two have been translated to English so far. I'll have to learn Danish so I can read the rest
