Any fantasy or other books with amazing character arcs?

I recently watched Game of Thrones and the Harry Potter movies and also read the books. I absolutely loved them, especially the characters and their development.

Two characters that really stood out to me were Snape and Jaime Lannister. I loved how complex they were and how their character arcs slowly changed over time.

Now I’m looking for new books or series to read. Fantasy would be great, but I’m open to any genre as long as the characters are really well written.

Are there any books or series you’d recommend that have character arcs (or even better than) these? Stories with morally grey characters, redemption arcs, or really deep character development would be perfect.

Thanks!
