please recommend popular fantasy books for adults

tldr: there is no useful information I can give other than the title, I haven't read many books but I'm sure there's no comparison between them and games

I tried listening to harry potter audiobooks but a few books in I gave up it's too childish for me, it's the perfect kids series which would explain why i used to like it so much but now every second I listen I'm thinking they should've changed this or that

I looked up what was like harry potter and got percy jackson, it was 10x worse dropped the first one 2/9 hours in.

books I've read are power of five and I liked it, forgot the author but it's about 5 kids with powers… I think it's the only book series i read apart from harry potter unfortunately

for more info I can only give examples of games that I like
metro- didn't like the books but games have great plot
the nier games are very immersive and a pleasure to play, I won't say I want to read something with the same feel because it'd be jumping the gun
final fantasy
souls games- love the lore and vibe of these
did not like dragon quest 11, saying this because it's very very popular even though it was extremely boring to me, no weight at all
