I think Annabeth is one of the seven based on what Juno told Percy in his dream. I think they put it out pretty clear. If Annabeth turned out not to be one of the seven I'd be really surprised, since I can't tell how Rick Riordan would make another child of Athena while they're about to go to Rome. It can't be anyone from Camp Jupiter so let's cross that off. It shouldn't be anyone from Camp Half-Blood unless Chiron sent someone or the child sneaked out to Rome. Or it could be someone they do meat in Rome. Though I just thought of evidence that Annabeth might not be the seventh. Juno told Percy Annabeth wouldn't be able to do something in Rome and would cause trouble for Percy. Maybe that's because she isn't the seventh?
