i think none of annabeth and reyna would be the seventh since the two of them weren' t given the spot to narrate in the books. i hope hazel is demeter/ceres' daughter since the godess seems weak yet her role (fertility) is important. she must have a daughter for a change. :) but if hazel isn't her daughter, i hope the seventh would be hers, apollo, artemis, or hestia. i know that artemis and hestia are virgins but who knows? riordan is good at twists in his stories. and he can find a way if he wants to. i think frank is ares' son. just a feeling. :)
