Also, did anyone else have a feeling that Hazel's POV would be first? She is the daughter of Pluto/Hades after all. And if you look at all the other first chapters of the other Heroes of Olympus books, they have the demigod's POV first of whoever's godly name is in the title. I'm sorry I am really bad at explaining things but here are some examples:

(The Lost Hero doesn't really count since that did not have a god's name in the title. Unless you count Jason being the lost hero to the Camp Jupiter...)

The Son of Neptune: Percy's POV was first

The Mark of Athena: Annabeth's POV was first

The House of Hades: Hazel's POV will be first
