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.

With mysterious clues all pointing towards the Son of Poseidon, Harry knows he will see his cousin again soon.
