There's a little problem with your idea of a sequel for the HoO series. Riordan can't ride the Percy Jackson train forever, plus there are only two major wars that truly involved the gods, and no I'm not talking about the Trojan war I MEAN truly involved the gods as in they took part in the fighting in Greek Mythology. The first was the Titanomacy which was covered in the original series and now the Gigantomacy which is being covered in HoO. There's not much else he can write about for either Kane or PJO/HoO. Kane's were basically following the basis of all Egyptian Mythology which was the end fight between Apophis and Ra.
