Looking for epic fantasy with real moral conflict

Lately I’ve been really interested in stories where the conflict between light and darkness isn’t just external, but internal.

Where characters are forced to make decisions that change who they are.

Any recommendations like that?

If you are trying to find an audience for you own books there is a group here specifically for that: https://www.librarything.com/ngroups/8391/Hobnob-with-Authors

I am assuming that is your purpose as the only books in your library are your own.
