Harry Potter always knew he was different. Even by wizarding terms. He could never explain it so he stopped trying. He brushed it of but knew deep down there was something else. He knew many things like the fact that dumbledore was a manipulative bastard who payed people to befriend him. He knew the 'true' him would never belonged so he stopped trying and hid himself away. He built a wall around his heart never letting anyone in. He put on a mask and started acting like the perfect golden boy that Dumbledore wanted. Nobody noticed. Nobody cared. He didn't mind. Meanwhile the Big Three Gods are mourning the loss of the son they created together long ago when they hear word of a boy who looks like them with unique powers like theirs attending Hogwarts school of witchcraft and wizardry. They go over to the school and enrol as guests to befriend and get back their long lost son. But is he willing to just let them in? Bit by bit they break down every defence mechanism Harry put up and see the broken boy behind the invisible mask. But with the Triwizard tournament coming soon it becomes apparent someone wants him dead. When he is chosen as a champion he doesn't know what to do. Luckily the Olympians are there to help.

Sally isn't who she think she is, she thought she was a average muggle, pregnant with her first child, by Poseidon, and just Poseidon. No, it was all a lie. She finds that out one night when she comes home to find Percy half to death on her living room floor getting beat, again by the man she married to protect him. She's isn't Sally Jackson, she's Lily Potter neé Potter. She has another son, Harry, a year older then Percy, and Percy has two father's, strange but true. She remembers everything. And she's getting ready to go back. For Harry, for Percy, and for herself. **** Sally is not the main point in this, Percy is. And Harry. Crossover of course as you can all tell. Yaoi, Boyxboy ships will be in this, no Percabeth. And definitely no Hinny. I hate Ginny to be honest. Also OOC, and Soulmate Au in a way. DISCLAIMER: I own nothing but the plot. Not all, just my own mixed in. Now, go and enjoy!!!

Zeus must've said something because Poseidon visibly sighed and looked away with a dangerous scowl. Perci's father collapsed into a puddle of sea water, disappearing to...wherever. Zeus coughed, clearing his throat and raised his glass once more. "Odin, the Allfather and I have declared an alliance between the Greeks and the Norse." It suddenly seemed like a moment to hold one's breath and the whole room did, "With the marriage of Thor Odinson and Persephone Jackson." Silence reigned over the room for a few moments before the quiet was broken with the shattering of glass hitting the marble floor. All eyes turned to the culprit, it being Perci herself. Annabeth was looking at her, shocked beyond comprehension and a hand covered her gaping mouth. Piper and Hazel's reaction were similar. The sea green eyed demigoddess took a shaky breath, a handful of her skirt and fled the room for the closest door. The only sound was the quick tapping of Perci's heels hitting the marble floor and the mountain quaking beneath her. Complete 14th of September 2018 Edited 18th of January 2019

I know there are plenty of stories were Percy Jackson and the demigods of Camp-Half-Blood come to Hogwarts, but what happens when the demigods aren't the only new students enrolling in the magical school. Percy and his friends are as surprised as the Hogwarts students when the new wizards are announced. Morgana, Morgause, Morgara, Mordred, Nimueh, and of course Merlin. Good luck to all witches and wizards, your battles have only just begun. . . . I completely messed up while writing this so the story has no particular time frame and most of the dead characters are still alive . . . I'm really bad at updating just so you know
