A problem I found with this book was that there were too many view points that didn't offer anything meaningful. Piper is sort of just there, and more worried about her relationship. Sadly, Percy also seems like a filler character. He has a few concerns but I don't think his POV added much besides that. Annabeth and Leo combined told the story well and the thoughts of the other characters could've been told somehow through their chapters. I almost wish Frank or Hazel also had a POV but I suppose that's for the next book.
