Books where one character helps/forces another to overcome a fear?

I'm looking for books where a character helps another character conquer a deep-seated fear or at least helps them/forces them to face it. It could be anything—fear of heights, goblins, dragons, touch, the dark, relationships or even something more abstract like fear of failure or vulnerability.

I’d love recommendations where this is a meaningful part of the story, whether it’s through friendship, romance, mentorship or any other dynamic. Bonus points if the book has strong character development and an emotional payoff.

Any genre is welcome, but fantasy is my favourite.

Thanks!
