Summary
Percy’s mother was nice, pretty, caring and terribly unlucky.
Percy knew that. He knew that his mother had been through a lot, and he also knew that the tale she had told him, about parents that died in plane crashes and uncles that died of cancer, was not the truth. Or at least not the entirety of it anyway. He still remembered the one time he had found this book squashed somewhere in the last nook of the bookshelf. It was a deep green and when he opened it the name Saffine Riddle was written on the upper left corner in neat letters.
Or: When a long forgotten letter resurfaces, secrets of the past start to unravel that might change the course of history forever.
Or: The one in which Sally is Voldemorts runaway squib daughter, the Gods have beef with the wizards, Percy is going through divine puberty, English weather sucks even more than usual, Dumbledore is suspicious, the Golden Trio are surprisingly apt detectives, the Slytherins fancy themselves traditionalists, everyone is prone to joining cults and Snape is just trying to teach potions.

Summary
She was dead.
Or at least, that's what he had been told. Killed by the Order of the Phoenix. However, that was a lie. His daughter had been living a life separate from him all these years. That was unacceptable. No matter how silly her ideas about muggles were, he held love for no other in the world than her. And he would make sure that Sally came to him, no matter what.
Sally had been living for years as a muggle. She put her wand away when she ended up in that orphanage, and she has kept it in a box for years. However, when two groups of magical people show up at her home looking, not for Percy, but for her, she has to make a choice on whether to continue pretending, or to open up that box and show her family what she was.

Summary
Percy Jackson can’t get a break. He stopped the fall of Olympus. He stopped the rise of Giants and the destruction of the mortal world. He finally, FINALLY, got into college. His life finally looked like it was getting better. So of course he’s not even a little surprised when he gets kidnapped by a group of wand-waving weirdos who took a little too much inspiration from the Fairy Godmother from Cinderella. And of course, his other grandfather was one of those weirdos. And also of the psychopathic, murdering, dictator variety.

Summary
“I pulled up a phone book, Ron,” Hermione explained. “A name and last name is all you need to find just about anybody with it. The chart just helped us narrow it down.”
Ron gave her an unimpressed look as he gingerly held a large yellow book. He handled it as if it would bite him if he moved it the wrong way. Harry was reminded uncomfortably of his Herbology book, dreadful thing it was.
“Muggles don't care about any sort of privacy do they?” Ron frowned.
Percy Jackson, the son of Sally Jackson and an unknown man. That’s all they could dig up, but when it comes out that he’s the grandson of Voldemort and he’s gone missing? It’s a race against time as the golden trio work against the forces to not only bring a missing child home - but to also stop a new dark-lord from rising.

“Yes, my lord” she murmured demurringly, her eyes never once leaving the floor as she bowed her head in supplication. The infant in the cradle made a gurgling sound as if it wanted to voice its agreement.Saffine, he named her. Saffine Riddle.
And for a while, that had been that.
Or: What happens to secrets when nobody is alive to keep them?
