Sorry I'm giving you a hard time, and it's greta that you have the originality to make up your own character for 'Class of the Titans' but two things. It's called Olympia High, and your character seems kinda Mary-sueish. Atlanta is supposed to be super fast, and that's a gift she gets from Artemis, so to take that away for some new character that appears seems kind of wrong. Plus, all the guys in the gang probably wouldn't gawk at Helen(Neil is full of himself, so he doesn't care, Jay likes Theresa, and Archie likes Atlanta). I hope you take my constructive criticism well, and use it in your next story(Half a Goddess 2).

ya i realized it was Olympia High after i was done typing that part, and sorry but Helen just was meant to be super-fast since her ancestor Hermes.
