There's only four point of views in this. Rick Riordan has done different people every time. He might make the POVs completely new characters! But I hope it's: Annabeth, Jason, Percy, and Hazel. Maybe Leo instead of one of them.
Actually, I think multiple points of view are a weakness for Riordan, even though the Son of Neptune was well done. The Lightning Thief series was the most successful, because we stayed with Percy. Hopping from Carter to Sadie and back again in the Egyptian series kills the momentum.
Leo's POV is after Annabeth's! I don't know the others. You can read the first few chapters of The Mark of Athena at http://books.google.com/books?id=gHoLiOEdoLoC&pg=PT5&lpg=PP1#v=onepage&q&f=false. They're really good! I'm not sure why we're allowed to read them (though I'm glad). The reunion's in it and everything.
well I dont care whose POV we read through just so long as the book on a whole is good. now I know Jason & Percy are most likely going to picked.annabeth is a going to happen. as for the others "??????????
The POV's are Percy,Annabeth,Leo, and Piper. Although I hate to admit I was EXTREMELY disappointed at the end and i'm sure most people will agree with me, it's the saddest ending I have ever read, kind of a romantic tragedy, it was the first book I actually cried at the ending.Hope yo enjoy the book as much as I did, it will take FOREVER for the next one to come out!
