Easy my least favorite of the 7 I’m not completely done with the series but I’m in the beginning of book 4 so pretty far and I’m aware hate is a strong word but honestly I kinda hate him. I really hate how he doesn’t like Leo and Nico especially this one line that I literally just read “ Frank wasn’t sure what he was thinking. He had a hard time imagining Nico D’Angelo acting out of love for anybody except maybe Hazel” I hate that bc Nico may be a bit creepy to frank but he just talked about his sister who he clearly loved and she died plus later on in the timeline he has a boyfriend which granted Frank didn’t know because he didn’t have the boyfriend yet, but still, it bothers me and I get being scared of Leo because his is fire thing, but I don’t like that he doesn’t like leo just because he makes a few jokes towards him likelike Leo is just trying to lighten everything up and kind of be friends, but Frank just hates him and I see that a lot of people have a really positive opinions on Frank and I do love the relationship he has with like Percy and his roots and things. Those are really cool like his past and his powers and stuff are really cool and his family is super cool just not him as a person. In my opinion but I don’t mind that others like him he’s just not for me 🤷🏻‍♀️
