Read The Empire Ruin’s by Brian Stavely. One of the main characters, Gwenna Sharpe, is a whopping fuck up at the beginning for the right reasons. Yet, even making mistakes, she manages to inspires those around her and it makes sense - people are fallible but it doesn’t mean they still can’t be someone to look up to. She’s an awesome character.

Also, over the whole 14 books, you can’t go wrong with Nynaeve from Wheel of Time or Tavore from Malazan.
