hmmm maybe Piper'll go on her own adventure back to camp half blood to stop the camps (being the 'mediatior' -maybe that's what her role is after all since she certainly doesnt have a role now). you're right about the title. a house of hades is probably going to be from percy and annabeth's journey in tartarus so we'll hopefully see their POV after all. the rest meanwhile will sail to greece battling monsters (i dont see how that can take up a whole book considering how close italy is to greece). maybe there'll be a twist and the doors of death were never in greece...and they fail to close the mortal side. and percy and annabeth manage to close the tartarus side and come out through the mortal side in the north pole or something.....okay i went off on a tangent but i just can't stop guessing and speculating!!
