Chapter 1: new worlds discovered (Leo Valdez POV)

"WWWWWWHHHHHHAAAAAAAAAAAAAATTTTTTTTTTT!...Wait What?"

Chiron had just called a meeting; everyone was here including the hunters of Artemis and an Iris message to Camp Jupiter.

Chiron took a deep breath and said, "Until not long ago we believed that Greek demigods were the only un-normal thing around. But as we learned there is such thing as Roman demigods. Well….. what I'm trying to tell you is… there is other people out there, different people, like us but not quite like us."

"Just get to then point."

"In Britain, there is such thing as witches and wizards. And like Camp Half-Blood, there is an safe heaven for them too, called Hogwarts, a school for witch craft and wizardry."

"What do you mean, like... bip a dee... bop a dee ... boo, waving wands around and all that?" asked Percy.

Everyone sighed; the Stoll twins even took a face plant. THWONK! Annabeth slapped Percy on the back of the head "Percy you idiot! Of course their like fairy god mothers for Zeus sake!" Annabeth retorted.

Man i feel sorry for that dude, thought Leo, always getting hit in the head when he says something dumb, which it quite a lot, actually take that back, on an hourly bases. He must have a pretty hard head especially since its Annabeth hitting him. Oh dam ADHD acting up again of topic.

"10 people will go over, to Britain, for the whole school year and then 10 people will come here for the next year and summer" said Chiron.

"Who's all going" Piper asked.

"I got a list here:

PERCY JACKSON

ANNABETH CHASE

JASON GRACE

PIPER MCLEAN

HAZEL LEVESQUE

FRANK ZHANG

THALIA GRACE

NICO DI ANGELO

LEO VALDEZ

Everyone started shouting at once. Complaining and protesting.

"When are we leaving?" Annabeth asked.

"Tomorrow morning. So you better all get to bed, big day tomorrow." Chiron replied.

With a lot of moans everyone got up and left for there cabins. Better go to bed then Leo.

Harry's POV

I was sitting with Hermione, Ron, Ginny and Neville on the Gryffindor table in the great hall. It was loud and noisy. Everyone was excited for the new school year. I had my arm around Ginny's waist. Apparently there was going to be a big announcement from Professor McGonagall but no one was sure what it was about.

Everyone started to quiet down as Professor McGonagall stood up to make her speech.

"Now listen up everyone over this year we're going to have some witches and wizards from America staying with us and then a few chosen people from our school will go and stay at their school" whispers broke out around the room.

"When are they arriving Professor?" Hermione asked. "Soon, very soon. So everyone out to the front of the school," replied Professor McGonagall.
