This is my first fan fiction, but it hopefully won't be my last! It is going to be a fan fiction of when the Seven Half-bloods, Reyna, and Nico are invited to Hogwarts. It will take place AFTER the events of both stories, but most characters that died in the books will still be alive. Calypso may make an appearance, but I haven't planned it out yet. All characters from Harry Potter ARE NOT mine, they are J.K. Rowling's. All the characters of Percy Jackson and Heroes of Olympus are Rick Riordan's.

Percy's Point of View (POV)

As soon as I got home from the bakery in New Rome, I was greeted by an owl. At first I thought Uh oh, Athena thinks I have been a bad boyfriend and now she is about to strike down on me with all her godly powers. Then I realized, there was 2 letters attached to the owl's foot. Breathing a sigh of relief, I detached the letters from its foot and opened examined the one with my name on it. There was my address, and name on it, and on the back was a strange seal with a lion, badger, eagle and snake around it. Anxiously, I opened the envelope, and the letter read:

Dear Percy Jackson,

You have been accepted as an exchange student in Hogwart's School of Witchcraft and Wizardry. Due to the fact you are of mature age, however, you will take different classes than those of years 1-7. Enclosed is your list of needed supplies. We have paid for your flight to Britain, and there you will find a group of wizards in which we have chosen to guide you. We await your owl no later than July 31st.

Yours Sincerely,

Professor McGonagall, Deputy Headmistress

I stared at the letter, both amazed and confused. What was this? A practical joke from Leo? If so, why would he choose an owl to fly all the way from his mechanics shop in Camp Half-Blood to my house? And why does he want me to fly to Britain? Adding to the confusion, Annabeth's letter had to same seal on it, and Leo never even dares to try to prank her. Speaking of her, she is rushing home from the library just now...
