Well today I was reading my copy of Percy Jackson and the Sword of Hades (yes i do have a copy of it outside of demigod files) And it says "Christmas in the Underworld was not my idea".
But if they live in a world of Greek Gods wouldn't their be no Christmas for demigods. I mean you cant beilive in God,Jesus and Zeus at the same time can you? No.
So I think there should be no christmas in PJ. Leave your thoughts in the coments
