the world is a game of chess. every move you make, someone is watching on the other side of the board, planning to strike you down. aradia was a pawn. that, she had always known. she was a tool made to be used in someone else's war. but even still, she fights through every scheme, trap, knight and rook. she fights, because it was what she was made to do, for every chess piece has its purpose. and even a pawn can checkmate a king. ========================================== It's a strange thing to find out that all the legends you were told as bedtime stories growing up were, in fact, real. In this world of titans and gods, magic and monsters, Aradia just wants to survive long enough to really live. But there's something deeper and ancient that lives within her soul, and it's coming out to play whether she wants it to or not. Join Aradia in her journey through both the wizarding and demigod worlds as she uncovers thousand year-old secrets that connect to her past and finally becomes the person it takes to play the game.

Sally died protecting her nephew Harry Potter. Lilly and James Pottor come back home to see her dead and Harry crying. But they notice something else is wrong. Their nephew Percy is gone. All rights go to Rick Riordan and JK Rowling So in this story there is going to be a lot of people who aren't dead. There's Snape, Sirius, Lupin, Tonks, Lilly and James (of course!). Also Fred not going to be dead because separating the Weasley twins is like separating the Stolls! Blackjack and Percy are going to seem more close in this. I've only seen the movies to Harry Potter so sorry for incorrect information! Just tell me and I'll try to fix it!

(A Percy Jackson and Harry Potter Crossover) Percy Jackson was hiding. This time, at least, it wasn't from mythological Greek monsters. No. He was hiding the truth from everyone. Born in England, growing in an abusing atmosphere, the older brother of "The chosen one", the first demi-wizard to ever attend Hogwarts, two times saviour of Olympus, Percy Potter had a lot on his plate. But he couldn't tell that to anyone until his coming of age, or both of his worlds would crumble, and it'd be his fault. Join Percy in this awesome story, where he will overcome the hardships of...well, being himself. TRIGGER WARNING: Mentions of Abuse, and some cursing! (Not too much, just a bit sometimes...). I own the plot and nothing more! [Won't update for a while]

Percy is betrayed and goes to Hogwarts with the help of Hectate, Poseidon, Hermes, Apollo, Hestia, Hades, and Artemis. Since he has books written about him, everyone knows about Percy Jackson, so he must wear a hood. What happens when his secret is revealed? What will happen to Camp? Am I craving Coca-Cola at 10:26 pm? YES!!! Any ways, I will go ahead and say this here: I don't own Percy Jackson or Harry Potter! And thanks SO much for the cover @TyeDyeRainbow! Check her out!
