good fantasy books?

so i recently started reading started with harry potter all books after seeign the movies for a billionth time then i read dan browns inferno and lost symbols those i read in dutch and then i read the circle in english which i wasnt that big of a fan of

but my most recent book was the never ending story in english my first real fantasy book maybe u could classify harry potter but its not on the same level of fantasy as neverending story with like imagenation

i really enjoyed the first half but i disliked the 2nd like it started out good but i wanted to see more of atreyu and falkor i really love them and i absolutly hate bastian going on a power trip but i finmished it and now i need a new book

preferably something that can be found in librarys doesnt really matter for me if its in english or dutch

and if it matters im 15 but im fine wwith more darker (i actually prefer that) and lighter themes
