Perseus Jackson was a strange person, Harry decided. He came from overseas, had the weirdest American accent, spoke strange sayings, had ADHD and dyslexia, and stood up for every kid. He was a Gryffindor, but consorted with Hufflepuffs, Ravenclaws, and even Slytherins. Perseus Jackson was a weird person, Harry Potter decided. But he wouldn't have it any other way.

*I looked at Annabeth "What do we do Wise girl?" "Attack?"* *"Percy!" Annabeth screamed a late warning.* *"Potter. A pleasure to see you again." Voldemort lifted his wand.* Basically the title says it all: A Percy Jackson and Harry Potter fanfiction with a tad of Doctor Who

This story takes after Heroes of Olympius and Deathly Hallows. The demigods: The seven, Nico di Angelo, Will Solace, Reyna Avila Ramirez-Arellano Thalia Grace, Calypso and Rachel Elizabeth Dare were sent to Hogwarts to study and make allies. But when they arrived, they were mistaken as Death Eaters by Harry Potter, Hermione Granger, Ronald Weasley and Ginny Weasley. What will happen in that school? Will they have a normal year as they wish or will they get into trouble again? I do not own any characters but J.K.Rowling and Rick Riordan does.

[1] New Beginnings: WARNING!! Story is technically complete but I started editing literally years ago then never finished so the beginning's a little funky! Percy Jackson was adopted at the age of seven by the nastiest family in the world: the Dursleys. He met Harry Potter, the most wonderful person in the entire universe, that same day. Though completely unrelated, the boys were nearly identical, a connection forming between them that would last years to come. The pair would go through life as brothers in everything but blood. Connected at the hip, these seemingly average boys had much more in store for them than they could ever imagine. A note: Percy Jackson doesn't discover anything about the demigod side of his universe until later in the second book. Just a warning. If that's too slow for you, don't read. DISCLAIMER Note that I do not own anything that was created by J. K. Rowling or Rick Riordan. I only own some of the plot and the occasional person or place that I may create myself. WARNING When people comment mistakes, I come back and I make sure that they're fixed. So, I'm still editing.

[2] Diverging Paths: Perseus Jackson, also known as Percy, left his first year at Hogwarts School of Witchcraft and Wizardry feeling happy and confident that he had actual friends. However, that was before they seemed to forget all about him. He at least had his brother, Harry Potter, but he too had gotten no letters from their friends. Then one day a small creature wearing a pillowcase showed up in their shared bedroom and told them that they absolutely, positively could not go back to school under any circumstance. Of course, the small creature wearing a pillowcase was resolutely ignored and they went back to school to start their second year anyway. Then things started to go wonky, what with all the strange voices and massive spiders. But then things got even stranger. Water seemed to bend to Percy's will and he kept feeling as if the forest was watching him. DISCLAIMER Note that I do not own anything that was created by J. K. Rowling or Rick Riordan.

Hermione Granger has brains, as everyone knows, so it's not very odd that she would be tutoring a few Hogwarts students who perhaps lack in their studies. But what happens when the student she is tutoring is no other than Draco Malfoy? Why is Dumbledore so keen on Hermione tutoring Draco even though it's against his will? And why is Draco feeling a little warmer towards Hermione despite his usual cocky, arrogant, and sarcastic comments? Well, all the answers are in this story of course!

I guess it's going okay- I mean, a houself tries to kill me all year, there's this beast petryfing muggleborns... Ginny and I have been so confused. Our memory is going haywire... Chicken feathers are on our robes.. I see to be dying on the inside and out. I think I'm the one... Me and Ginny, that is... I'm Madison Potter, and the Chamber of Secrets has been opened. I DONT OWN HARRY POTTER
