So, I hate all those fanfictions that don't go by the books very well, no offense if you're one of those fanfiction writers. So if you see something here that annoys you or just doesn't go by the books, comment! I want to know so I can fix it. Also you might need some google translate, so I'll try to add the translation in for you! Bolded is in Ancient Greek or Latin, depending on the demigod speaking it.

It hurts you know, betrayal. The pain slowly eating your heart, the words stabbing you, the negative thoughts circling your mind. Have you ever felt that pain? I did. When my friends believed an idiot who couldn't even hold a sword, when my father disowned me, when my girlfriend cheated on me. I left carrying that burden in my heart. Now after so many years, that pain still lingers in my heart, I slowly believed on the words that stabbed me, back and front, and the negative thoughts never left me. And I covered it all up with a smile. But I had to go back, damn fatal flaw, I need to go back. Not just to save them but to save me too, to bring me back, to bring Percy Jackson back. Because 10 years ago... They already killed him. ¬¬¬¬¬¬¬¬¬ English Started: October 2k15 ©Janalecksa

In the worlds of Harry Potter and Percy Jackson, Harry is eating dinner in the Great Hall and Percy is being chased by monsters. How do the two worlds meet? Simple. Percy falls through the enchanted glass ceiling of the great hall unconscious. Percy doesn't know where he is, only that he's being chased by monsters. Fighting in the sky with Blackjack, there are only two monsters left. The monsters hit Blackjack and Percy with their clubs upside the head, rendering them unconscious and spiralling in different directions. As Percy plummets downwards, Riptide slips out of his hand and slices through the two remaining monsters, killing them out of pure luck. Or is it pure luck? When Percy wakes up in the Hogwarts infirmary and tries to leave, Hecate tell him to stay and protect the Boy Who Lived and his two closest friends. Except how is he supposed to protect people that don't trust him? Disclaimer: I do not own PJO, HOO, or HP.

All is as it should be. Percy Jackson and Annabeth Chase can finally relax after Gaea has returned to her slumber. Both are alive and excited for their future. But what will happen to their plan of college in New Rome when two meddling goddesses interfere once again? This time it's only a job for the Dynamic Duo. The rest of the Seven have earned their peace, but apparently Percy and Annabeth have not. They find out that not only are Greek and Roman gods real, but another myth is not such a fable. Their next journey will take them to Europe--to the Hogwarts School of Witchcraft and Wizardry. Harry Potter and his friends have finally beaten the Dark Lord. Voldemort is gone and all they want is a normal, uneventful year. Returning to pass their seventh year of magical studies, the Golden Trio finds that their troubles are far from over. Two new students join the misfits of Hogwarts and Harry, Ron, and Hermione do what they do best-dig deep to uncover the skeletons in Percy and Annabeth's closet. Little do the wizards know that the demigods are already on to them, and doing everything in their power to protect their secret. What will happen when all of the cards are on the table? Will they put aside their differences, trust each other, and work together? Or will the world witness a monumental battle between the Golden Trio and the two-time Saviors of Olympus?

The Seven, Calypso, Nico, and Thalia are going to Hogwarts. What surprises lay in store when they have to defeat Voldemort? Again! Takes place after The Blood of Olympus and The Deathly Hallows. Disclaimer: I don't own anything, Rick Riordan and J. K. Rowling do. Highest Rank: #741 in Fanfiction

Harry stared at me. "You're just like him. Looks like you do take after your uncle," He sneered at me with an undertone of sadness," He killed my parents and tried to kill me, too. Is that what you wanted to hear? When I was eleven, eleven, He came back as one of my professors. He tried to make himself come back. But I beat him. Then," He pointed at Ron,"His little sister was possessed by the man who ruined my life. He almost got back, but we destroyed the diary and saved the muggle-borns. Then, I find out t hat my godfather was an evil mass murderer but he was actually innocent. Then, Ron's rat turned out to be Peter Pettigrew, who was Volde-" "Harry, no! You can't say his name!" Hermione burst in. She looked afraid. "We'll have to face the death eaters and we're not ready for that." "'Death Eaters'." I said in disbelief. Trying not to laugh, "Who would want to eat Thanatos?" ************* This takes place after Blood of Olympus, before The Hidden Oracle, and during Deathly Hallows. It is mostly in Harry's and Percy's point of view but a few others are thrown in. I worked really hard on this and I really hope you guys enjoy. The first couple of chapters are about 500 or so words but they get longer, I promise. If there are any spelling mistakes or grammar mistakes, feel free to comment them down below. It is an alternate ending to Deathly Hallows. Please don't kill me when you read the bonus chapter/ epilogue. In your demigodishness and all that, stay potterheads. Love you guys! Thanks for reading!

The Seven plus Calypso, Nico and Will must go to Hogwarts to befriend the Wizards.

SLOW UPDATES! I MEAN LIKE REALLY SLOW. LIKE I UPDATE 4ISH TIMES A YEAR. I'M NOT GIVING UP ON THIS STORY THOUGH. A prophecy sends eight demigods to Hogwarts to defeat two powerful enemies. Warning: There will be occurrences of Percabeth, Jiper, Frazel, Hinny, Romione, and others. There may be some swearing in this book. Enjoy! I in no way claim these characters or worlds. All of the demigods/ sayters/ centaurs/ mythological monsters/ gods personalities/ etc. belong to the amazing Rick Riordan. All of the witches/ wizards/ spells/ magical monsters/ etc. belong to the wonderful J.K. Rowling.
