My guess is that it's gonna switch to Percy & his friends' POVs in the Roman camp (maybe third person, too, like Jason, Leo and Piper's), telling their own adventure during the events of the Lost Hero. either that, or.. maybe events that will happen a few weeks/months after that book.. Whatever it is, Percy will be a big part, hopefully. :D
