Women’s Prize for Non Fiction

I am really excited about this list, my mother and I read the entirety of the Women's Prize for Fiction a couple of years ago, it took us 14 months but we are still proud of it.

So this year we decided to try reading some of the books from the second Non Fiction year.

Only I realized Why Fish Don't Exist (a book we are both excited to read) was published in 2020… what gives? I would have assumed the books in the 2025 list would be from 2024. Are there so few good non fictions written by women? Are we also scoring the books on impact?
I looked at their website and they don't seem to have an answer….
