hey i think that RR is bringin the whole greek myth thing to a close as it is mentioned that all though the gods power is in america but it comes from the original olympus the heroes also are headin to rome and the giants i think are planing to attack the gods at the core in the original olympus so if the final battle is in olympus and everything is goin back to its origin do u think this is the end for all the greek myths in rr novels
