uuuh interesting so what i would say is my all time favorite at the moment is 'Never Let Me Go' by Kazuo Ishiguro
I also love 'One Day' by David Nicholls, I loved the movie and even more the book though I read a few years ago so I'm not sure it would be in my favorites if I were to read it now (I do think so?)
I'm also a huge lover of crime novels especially Agatha Christie and yeah my favorite from her are the basics ngl haha so 'And Then There Were None' and 'Crime on the Orient Express'
And finally my top book I read last year was 'In The Dream House' by Carmen Maria Machado and it has REALLY stuck to me so I think it would be fair to put it up there with my other favorites 💖
