Either Percy or Annabeth needs a POV, or else we'll have no idea what's going on in Tartarus xD

Jason, Hazel, and Frank should have one too.

However, I really wish Nico will have a POV! We need to know what he's thinking about all the time, plus he's on the ship right now. He deserves to have a POV for once! Oh, and he has a ton of fangirls. Good enough reason. x3
