You have a pretty good story going here...the OC seems more than a bit Sue-ish, I won't lie about that, and it's actually really, REALLY annoying how you seem to have to describe what new outfit she's wearing every chapter, but it's not too bad of a story. Your spelling and grammar, at any rate, isn't too bad, which is astounding for this fandom.
One thing I feel the need to comment on...oh hell, I'll just say it...lay off of Eliza Cuts, will you? I'm so sick of seeing people bash her. Maybe she was a bitch that was using Gee, and deserves to be hated. Maybe she's not. How are we supposed to know? We don't know her, we don't know what happened between her and Gee, and seriously...all of this immature Internet hate for her is both tiring, and frustrating. I'm sick of seeing people bash her in various ways in their fanfics...no one deserves that much hate, no matter how much of a bitch they may or may not be. Would you like it if your engagement ended, and suddenly people all over the Internet were writing you into their stories as some jealous bitch? No? Then be a rebel against the cliches, and cut it out, will you? It's overdone, and childish. Poor Alicia had to go through the same shit, and still does. Just let it go.
