I read 27 books in 2023, and while I enjoyed most (no dnfs), these... challenges my patience:
The Real Valkyrie: you can't call a book factual and then have 70% of it be made up, fictional, story with the barest support in archeology.
Girly Drinks: often ignorant author who seemed more interested in going "yay, booze!" than in having any kind of in-depth analysis of how at times, alcohol has actively made the lives of women worse.
