I reckon the Greeks will go to Camp Half-Blood, fight the Romans a bit, show them the statue, make up, go to doors of death and cliffhanger.

Fifth book: Close the doors of death, go to Greece, massive fight (possibly see Carter and Co), then live happily ever after. The End.

Oh, and another thing, I don't like Piper. All she talks about is "Jason this" and "Jason that". FOR GODS SAKE GIRL, THIS ISN'T TWILIGHT!!!
