As far as POV go, I'm looking at all the naarators so far and only Jason, Hazel, Frank, and Annabeth have narrated once, meaning they are the most likely to have a POV in the next book. If Rick only uses three, I'd have to go with the Roman demigods only as the MoA was all Greek. That is just my view however.
