I think Riodan will have the pov&apos;s of Jason, Piper, Leo, Frank and Hazel in House of Hades, keeping Percy and Annabeth in Tartarus a contiunous suspense. I don&apos;t want to say it but I believe that Percy will be the one to stay in Tartarus to close the doors, as Mars told Frank in Son of Neptune, that Percy has a great decision to do in the future which could either save the world or not. I also believe that the oath is Percy and Nico&apos;s promise at the end of Mark of Athena.

But I voted to Percy for POV, because I just love the guy, he is my favourite out of seven besides Annabeth.
