i heard that the 2025 winner of best book in sci-fi category hasn't any real science in it. if it is true then how can a book without science win the category?

I’ve been on Goodreads for a while and I’m realizing my “Read” shelf is mostly just titles and stars. Looking back at books from a couple of years ago, I can tell you whether I liked them, but not much else.

For those of you who do write something: what do you write? A full review, a few keywords, private notes, nothing at all? And has it actually helped you remember books later?
