Literature.

Ladies and gentlemen... I want to note that regardless of the genre (personally, I like science fiction, fantasy, detective stories, historical novels... and even, recently, poetry), I, as a reader, evaluate the actions, experiences, and thoughts of the characters, as well as the author's writing style. After all, when you read, you also empathize with the events together with the heroes...
Sometimes, depending on your mood, thoughts from a book resonate very strongly and stick with you (especially poetry).
After all, sometimes you ask yourself - how would you act in a specific situation (from the book)...
A book can both raise life questions and provide answers to them.
And the genre of the books is irrelevant here.

What books did you start reading but never finish?

I can manage to read different books... but I still couldn't finish reading Dondova.
And usually, it's the other way around, when you reread something after some time... and you find something new for yourself.
