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!!!

(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 Jackson, Annabth Chase, Nico Di Angelo and Thalia Grace go to Hogwarts. The usual quest to protect Harry Potter and the golden trio. My version though. Set after BoO and during Order of the Phoenix. Percabeth, maybe Solangelo. Ron and Hermione. Harry and Ginny. No Cho I think. Yey my first story on whatpadd and hope you like it.
