inej ghafa is such an incredibly refreshing character to see in ya literature today.
obviously she's badass, she can fight, she wields knives, but she's never reduced to being the love interest in the story. her character development has, quite frankly, nothing to do with romance and it's mentioned several times that she will not try and heal kaz just to be with him.
she acknowledges that both of them have demons to face and struggles to overcome but she accepts that she cannot force a person to become someone else, no matter how much you might want to. she lets kaz decide for himself that he wants to become better for her, and she refuses to settle for less than she deserves.
i'm a sucker for characters healing together but i love this. they heal together but their journey is never wholly dependent on the other. they also accept that they have different goals in life, that they don't always have to be together to grow. it's realistic, and almost never seen in fantasy (or ya lit in general) where so many plots involve the bad boy™️ being "tamed" (for lack of a better word) by the girl.
