User blog comment:Awesomeness34/Thoughts on Son Of Neptune and The Lost Hero/@comment-4528975-20111212002614/@comment-4515675-20111212080358

Actually in SoN the only character who truly was a son of Neptune was Arion so the theory that just because the next book is called MoA Annabeth has to be the seventh pretty much goes down the drain. For the last time, did Hera say that Annabeth was one of the seven? No. She said she will cause trouble for the quest, don't misunderstand this.

I don't know if Annabeth is really part of the prophecy or not but if you stop to think about it, RR is playing with fire right now. If he makes Annabeth one of the seven then it will be a painfully boring outcome because 99.9% of the fans already expect it to be her so there's just no fun. If he doesn't make Annabeth one of the sevens it will be interesting because it will leave us guessing who the seven will be but if he's making a new character he should already expect a lot of hatred for him/her because fans won't take it lightly that Annabeth isn't the best child of Athena/Minerva. My theory is that if he doesn't make Annabeth the 7th he will go with a character that we already know or met but didn't think much about him/her and probably not make him/her a direct child of Athena/Minerva but a legacy instead. After all in the Olympian week he never stated that the said god/goddess if the parent of the hero.
