I think it should be Nico De Angelo's, Percy&Annabeth's, and Leo's Point of View. Hopefully we can get a glimpse into Nico's head as he's the only demigod who's seen and known everything going on for awhile now. I think we NEED to see things through Percy and Annabeth's eyes as well as theyre going to be going thru the BIGGEST and MOST DANGEROUS (and yes, romantic) quest/adventure off all the books combined.

Another idea could also have the book just focusing on the ARGO II 's journey to the doors of death and updates on Camp Half llod and their stand against camp jupiter's attack. Then follow and Percy and Annabeth in the final book.
