This book is based at the end of Heroes of Olympus, and the second book of Harry Potter. At this point in the story J.K Rowling has already written the first Harry Potter book. I do not own ether Percy Jackson, nor Harry Potter. I am very sorry about my spelling mistakes, I can't spell, and auto-correct isn't helping! PercyJacksonFan16 [Alex] inspired to write this.

Percy Jackson woke up one morning, with the sun beaming in on him through the blue stained windows. He could hear the dribble of the saltwater fountain, a gift from his dad, in the corner. It had stopped gurgling like a sick slug from the time Percy had basically smashed it in half, because Tyson had fixed it. Man, he was grateful for that now every time he went into his cabin, it no longer sounded like the faits had moved in, and were talking without their false teeth in. Tyson... Percy hadn't seen that big guy in a long time, he spent most of his time with Ella now, or in Poseidon's forges.

He got up, and got dressed, making sure to put on the silver watch Tyson had given him, which turned into a gleaming, handy shield, engraved with all of Tyson's favrout memories from the first quest we had been on together, and his bead necklace. There were, proudly, exactly six beads on it now, symbolising his six years at Camp Half Blood, the newest one was from the month before, a black bead with a white picture of a dragon figurehead. Feastus, the figurehead from the Argo II, it was from one of Percy's favrout [and embarrassing] quests. Percy stared at the bead, Leo, a son of Hephaestus, was Feastus's master and Leo had build the Argo II with the help of his half brothers and sisters. He had been a great friend always saving the day with his fire powers or his pen 'hot stuff' tattoos [long story], and he had sacrificed himself to save the world, and take down 'Princes Potty Sludge' as he used to call Gaia. Nico [a son of Hades] had sensed his death, but there was something off about it. "There was something strange about his death, like he had made himself his own rought into the underworld, a way that included some pistons, a spanner and some breath mints!" Were Nico's words, Frank and Hazel told everybody that Leo had the phsians cure, so there was some chance that Leo was alive. But how would he have taken the cure? Most of the Camp were looking all over for him, searching for any trace of him, they didn't even have a body to bury.

Percy heard a knock on his door, he trudged over and opened the door. Annabeth stood there, clutching a book, she looked at him with her innocent grey eyes. Percy gave her a quick kiss on her cheek, "what's up?" he asked, "we have a meeting in the big house before dinner, all of the councillors will be there, and I wanted to show you some blueprints that I have made for a structure in Olympus," she kissed him back and smiled. Annabeth wanted to be a famous architect when she was older, and she was in charge of designing a new Olympus, the place of the gods, after the titans in the second titan war had trashed the place. "Can you show me the blueprints later, because I have literally just got out of bed and I want some blue pancakes before we go to our activities," "I can tell! You look like a sleepy hooligan who has just fell out of bed!" She laughed.

When Percy was stuffed with blue pancakes, he and Annabeth headed towards their actives. Percy had sword practice, then ancient Greek lessons with Annabeth, grape squeezing with the Dionysus kids, chariot racing and then he climed the climbing wall.

Later, on the way to the meeting, Percy noticed some owls, streaking around the magical barrier that was not letting them into the Camp, and chirping at the magical berrier that was clearly not letting them in. "Hey, look Annabeth, owls, do you think it's a gift from your mum?" "Sure Percy, I'll do it in a minuet," she replied, her face in her sketched, blueprints and measurements for the new structure. "Annabeth! Listen to me," "Perc- oh" her eyes widened when she saw the owls, but she was not looking at the creature itself, she was looking at the piece of paper tied to its leg, a letter sealed with a big red wax 'H.' "I think I know why we are having a meeting."

In the games room was usually where they had meetings [yes they talked about the fate of the world around a ping pong table], at the head of the table Mr D was playing pinochle with Chiron and drinking his Diet Coke, the Stroll brothers were having a sword fight with the ping pong paddles, Clovis was asleep, which was no surprise, Kate Gardner was making flowers grow from Clovis's hair, Piper was talking to Jason and Buch, Clarisse was sharpening her knife and glaring at Percy, Nico was staring at the wall, meanwhile Will was fiddling with Nico's long hair, complaining that he should have a haircut, Thalia, a hunter of Artamis, was standing near Chiron, there were many more councillors in the room but Percy didn't pay attention too them as he sat down. Chiron clapped, and got everybody's attention.

"Percy and Annabeth have arrived, so we can start," Chiron said, nodding in their direction. "But not before the Strolls have but the ping pong paddles away, Kate has gotten rid of that nice, if I may say so my dear, but wrongly-placed garden on top of Clovis's head, I would ask Clovis to wake up, but we all know that is not going to happen any time soon, Clarisse please could you put your knife away, same for you Annabeth, with those notes, I know how important they are to you but I would like full attention, and knowing the Strolls, they would probably light them on fire when you are not looking. As some of you might have noticed there are a few owls trying to get into Camp, the Hecate children have confirmed that the owls are magical. And I have bee-" "A few owls!" Clarisse remarked, she stood up "they have been keeping my cabin and I awake last night. And It does not sound like a few birds', if I didn't know better I would say there was an army of them, they're so loud!" "Clarisse please I am-" "NO!" She flung her knife on the table, "This is Athena's fault, owls are scarced animal. You need to do something about it, Chiron!" Outside lightning flashed, and she gave Annabeth a cold stare. Percy was about to open his mouth and stand up for Annabeth, the owl was her Mum's scarced animal not Annabeth's. Besides, they might not even be from Athena! But Mr D spoke before him, "please kindly take your knife out of the table, Clarecia. I only bought it a century ago! Its new. And you do not want to know how many gold drachmas it cost me! Plus, these are not Athena's owls, I have spoken with the goddess and she says that they are not her's but they are messenger owls." Clarisse sat down. "My name is Clarisse not Clarecia," she mumbled, "whatever!" Mr D slouched back into his chair and took another swing of his Diet Coke. "So, if they are not from Athena who are they from?" Percy asked. Perplexed, he turned to Annabeth. "The symbol on the wax stamp is familiar, I think I've seen it before," she stated, and with that she pulled out Daedalus' laptop and started searching. The room went silent whilst everybody waited patiently, except for the Stroll brothers who were trying to light Clovis's hair on fire by rubbing the two ping pong paddles together, but Jason soon put a stop to that by summoning the wind to blow the paddles out of the boy's hands. "The Hunters of Artemus have come to help, hopefully one letter will be one for a hunter, if it is an enemy who is in charge of Hogwarts, then I want to know how they got the Camp's location. I might be a Hunter, but I care about Camp Half Blood too." She said from the corner. "Thank you, Thalia," Chiron smiled at the news.

"I-I think I've got it," Annabeth finally said, looking up at Chiron, they seemed to be having a silent conversation like, Hey, Chiron, is it really what I think it is? I am afraid so, child. Should I tell them? Yes, they are probably going to find out even if you don't tell them. "Hogwarts," Annabeth let that word hang in the air for a few seconds, "The Greek and Roman Gods are real and It appears witches and wizards are real too." "What, like that fictional book J.C Fowding wrote?" Piper said, she was dazzlingly pretty, but sometimes Percy forgot that every demi-god in this room are either dyslexic or ADHD, sometimes both, because of everything they had gone through together. "You mean J.K Rowling?" Buch enquired, "It doesn't matter, Buch, but yes J.K Rowling wrote a story about witches, wizards and Hogwarts, but my guess is that J.K wrote about a true story but passed it on as fiction, like Rick Rordan did." Annabeth explained, "Yes, yes, this is all very nice and dandy Anna Bella, but I do not see why Hogmorts would want to recruit some puny half-bloods to their fancy school," Mr D speculated. Percy caught Annabeth's eye, "They think we are Witches and Wizards!" They said together. "But we aren't, we are half-bloods, aren't we?" Will piped up. Annabeth slammed her face into her palm, "that's the problem, Will" "The only question is, who have this 'Hogmorts' chosen to go to their old school?" Mr D asked. "We will let the birds in at dinner, every single camper will to be there it's the perfect time to do it, but whoever is chosen, take great precurtain, this could be a trap set an enemy." Chiron said, "Meeting dismissed."

One by one, each councillor filed out of the room to tell their cabins and friends the news. Percy made a bee line straight for the beach, that was where he could think most clearly. A fictional book was real, well, if a normal mortal kid were to read Rick Rordan's books then find the Camp, he supposed it would seem like a book was coming alive, but this was different, a whole school full of potential enemies, learning magic that could sweep Percy off his feet. Percy sat down on a sand dune and was thinking about what other books could be real, when the water in front of him started churning, he leaped up, took the lid off his ball point pen, which then transformed into a huge celestial bronze sword, activated his shield and watched the water. A giant person, no, cyclops had come up from under the waves, it loomed over him, Percy got into a good fighting position and was just about to attack when a loud but cheerful voice said, "Percy! Yay, brother!" Percy put away his shield and pen and tackled the cyclops… with a hug. It was Tyson! "Sup Tyson, you startled me there, how have you been doing in the forges?" "Good, I am making big stick." He replied simply. "Boss has let me have the week off!" "That's great, man. I've got loads to tell you!" "Me too brother." Percy and Tyson began walking towards the Poseidon cabin talking, Percy told him all about the search for Leo and what they had discovered about Hogwarts. "So, is that why there are a lot of birds trying to get in?" Tyson queried, "Yup, and they are really annoying during the night when you are trying to sleep, but hopefully they will be gone by the time you go to bed so you wont have any problems, Chiron is going to let them into the Camp at dinner time."

As they walked, Percy saw the Dementor kids having picnics in the strawberry fields, the Apollo kids were having target practice and music lessons, the Athena kids were cooped inside their cabin, working, the Isis kids were making rainbows with random things, like water, a plastic bag and a bit of magic, the Nemesis kids were pranking people who had been nasty to them, the Hermes kids were delivering news and pick-pocketing people, the Aries kids were fighting and putting down bear traps, the Hecate kids were using the mist to become invisible then pop up right in front of someone, the Aphrodite kids were gossiping, the Nike kids were arguing about who's chariot was the best, the Hephaestus kids were busy in the forges, the Dionysus kids were trying to trip people up with their grapevines and the hunters of Artemes had set up their Camp a safe distance away from all of the boys. A normal day at Camp Half Blood.

Percy stepped through the door of the Poseidon cabin and the smell of calming saltwater reached Percy's nose. Sunshine came through the blue stained glass, bathing the room in a blue light, rainbows danced along the floor like fish swimming in the ocean from the dangling prism above the door and a soft carpet was stretched across the wooden floor with shades of blue on it. "Wow, this place has changed since I was here last…" Tyson said. "Yea, Annabeth said it was looking a bit dull, so she teamed up with some kids from the Isis and Hecate cabin to help mae the place more nice!" "I like it." Tyson said, plunking his tool bag on his bunk. Annabeth hadn't changed it completely; she had just added some things to make the room look nicer "Welcome home big guy," Percy said, "tomorrow we've got archery with the Apollo kids, then the Dementer kids insisted that I help them garden, then we have got dinner, a break then capture the flag. But now it's dinner time," he explained.

"The boys arrived at the Poseidon table, immediately a big plate of blue food appeared in front of Percy, and two peanut butter sandwiches appeared in front of Tyson. As they lined up to scrape some of their food into the fire Tyson mumbled, "goodbye peanut butter."

Once everybody had finished, the flames turned blinding white, a sign that the gods were pleased. Chiron cleared his throght. "Yay! I remember pony!" Tyson exclaimed happily, "remember, Tyson, his name is Chiron, not Pony." Percy remined him, Chiron cleared his throught again, to get everybody's attention. "Some of you might have seen or heard the six owls trying to get into Camp Half Blood," Chiron started, there were many mumbles from the campers and some scowls at the Athena table. "Some campers from the Hecate cabin have told me that they are not Athena's owls. However, they are magical. By studying the wax stamp on the letters they carry, Annabeth has found out that they are from the school, Hogwarts." There were some cries of disbelief and wonder from the tables. "Isn't Hogwarts a school from a fictional book?" Lacy, a girl from the Aphrodite cabin pointed style="mso-spacerun: yes;" pointed out. "Yes, before now, I was led to believe that the school was not real as well, child. But then how do you explain the owls. Annabeth and I think that J.K Rowling wrote the book Harry Potter a true story but passed it on as fiction. We are going to let the owls into Camp and see who will be going to Hogwarts. Whoever is chosen, I want you to go, but not tell anyone there that you are demi-gods. It might be a trap. If it is, I want you to find out how they got the Camp's location. Am I clear?" "Yes," everybody mumbled. "I hope that it's a trap, because then some of you might get caught and, yay, that's less paperwork for me!" Mr D added. With that happy note Chiron let the owls into Camp.
At first the birds squawked with joy, but then they came circling down, towards the campers. One owl dropped a letter on Jason's head, and then flew off into a nearby tree. Then another bird came down and dropped a letter into Thalia's hands, more birds came swooping in dropping letters for Annabeth, Nico, Will and then a letter fluttered down next to Percy's, now empty, blue plate. He ripped open the envelope, inside was two sheets of thick parchment. The first one said;

HOGWARTS SCHOOL OF WITCHCRAFT AND WIZADRY
Headmaster: Albus Dumbledorespan (Order of Merlin, First Class, Grand S forc., Chf. Warlock, Supreme Mugump, International Confed. of Wizards)
Dear Mr Jackson, we are pleased to inform you that you have a place at Hogwarts School of Witchcraft and Wizardry. We are sorry that we did not send this letter when you were eleven, we did not think that you were a wizard. Please find enclosed a list of all necessary books and equipment. Term begins on the 1st of September. We await your owl by no later than the 31st of July,
Minerva McGonagall Deputy Headmistress

"What does the letter say Percy?" Chiron enquired. Percy told everybody, and the Camp was so silent it could have been holding its breath, waiting for Chiron to say something. This was a huge shock, not only did they now know that the world of Harry Potter was real, but some campers were going to Hogwarts! "Jason, does yours say the same?" Chiron quizzed. Jason nodded. "Well then, the 31st is tomorrow, so you children had better start writing your letters back. But for the meantime, it's time to have our campfire sing-along. Everybody to the Campfire please."

While everybody was singing about how Grandpa sharpens his spear, Percy sat looking into the colour-changing fire. "Are you OK, big brother?" Tyson asked. Percy hadn't even heard him come up to him. "Yea, I'm just thinking. Turns out we can't spend that much time together, since, if I say yes to the letter, I will be on a train to Hogwarts in two days' time." "You will make the right choice, big brother." Tyson said confidently, "I know you will, I won't be hurt if you go to this school instead of staying at camp with me. I will look forward to when you return." He finished. Then he went to go speak to some Hephaestus kids who were wanting to know how it was like in Poseidon's forges. Still, did Percy really want to get caught up in a different magical world to the one he was used to? Was Annabeth going to say yes? With these questions in his head, Percy joined in with the last verse of the song.

Thank you guys for reading, this chapter had about 3,000 words, so please don't be sad if the next chapters are shorter, because I have to balance this with homeschooling. If you are a bit confused about what happend in this chapter; Percy, Annabeth, Jason, Nico and Will have gotten Hogwarts letters, and the Camp are still looking for Leo. Feel free to PM me, this is my first story on , so sorry if it is a bit rushed, cheesy or I have done something wrong. I'm still learning about how to publish, make chapters and so on, so i'm sorry if I do something wrong. I'll see you in the next chapter.
