I think it wil be the POVs of Jason, Piper, Leo, Percy, Hazel, Frank because we know for sure that they are a part of the seven. I think in The Mark of Athena we'll be guarenteed who's the seventh and then all of them will have their POVs. I think each person will get 1 chapter each. I think that in the Lost Hero and Son of Neptune there were only three because those were the seven that had a story to tell like Jason, Piper, and Leo with the the Quest to Save Hera and Percy, Hazel, adn Frank with their quest to save Thanatos.
