After the war with the giants is over, Percy, Annabeth, Nico, Thalia, Jason, Piper, Frank, Hazel, Leo, and some unexpected new friends are going to Hogwarts. Some people at Hogwarts know who is coming and what and who they are. Harry, Ron, and Hermione are coming back for their seventh year, to redo it after the war, and they didn't even go last year anyway. What will happen when the Golden Trio meets the Seven and their friends? Read on to find out. BTW, the ships included in this book are: Percabeth, Jasper(or Jiper-whichever one you like), Caleo, Frazel, Hinny, Romaine, Andrid, and Dryla. I'm going back and editing chapters as I write. If you have any advice or something that you think I should do or change, tell me and if I use it I will dedicate the chapter to you.
