Persephone 'Percy' Jackson has never been one to sit still, especially not at a desk, for hours a day, most days a year. After her thinning patience snaps, an inconvenient robbery and a well timed appearance from Bludhaven's hero, Nightwing, starts Percy on an exciting new journey. Now she's got a whole new set of problems, like managing her ruined sleep schedule and getting blood out of Kevlar. And who's that cop that keeps popping up everywhere? A Percy Jackson x Dick Grayson Story (also on ao3 and fanfic.net)

Nico di Angelo gets adopted by Bruce Wayne after Batman witnesses him stalking around a cemetery in Gotham in the middle of the night. He doesn't want to move in with Bruce, but seeing as he can't supply any proof of his parents or even his own birth records, he doesn't have a good reason to say no. It's Bruce Wayne or the foster system so Nico decides to take his chances with the billionaire. What he didn't anticipate is that he isn't Bruce's only child, or that the man is more than meets the eye. Nico gets dragged into the Batfam and has to learn their secret while trying to hide the mythological world from the greatest family of detectives in the world. No Nico ships. It would get in the way of the plot. I will try to keep at least somewhat accurate with the rest of the books. Everything belongs to Rick Riordan or DCU. (After pjo and before hoo) Please comment, vote, and tell me what you think! This book is currently being edited but I will still be updating. Updates are (really) slow.

1. Cliché stuff but Nicole di Angelo was shadow travelled into the beeping city of Gotham. What happens when a certain bat obsessed dude adopts her? 2. Neither @ilina20singh nor I own these characters. Do you really think that we'd be writing this if we did? Or that there wouldn't be seventeen seasons of Young Justice? We might add some OCs but we'll specify them then. 3. Don't be his friend. You know you're gonna wake up in his bed in the morning If you're under him, you ain't getting over him

Percy Jackson was just a little girl when she was stuck in an orphanage, where she met her childhood best friend, Richard Grayson. Despite how his charisma and charm got slightly annoying, Percy still tolerated it. Eventually, only days after joining the orphanage, a man named Bruce Wayne adopted both of them. They were a small family, but became close quickly. Until Bruce and Dick started keeping secrets. Bruce always was secretive, but not Dick. After weeks of getting sick of it, Percy ran away. She started a new life, with her distant family member, Sally. But after being rid of the Wayne family for years, Percy gets dragged back into it all suddenly, by her desperate cousin. But....Maybe this time wouldn't be so bad. *SLOW UPDATES* *IN THE PROCESS OF EDITING AND REWRITING*

She ran away and what will happen now that both wars are over and she returns to Gotham as Tidal Wave, a hero/vigilante??
