The Angel of Death

It's been two years since the defeat of Gaea, and Nico is finally returning to Camp Half-blood after spending the last couple of years collecting escaped souls for his father, Hades. However, just as things are regaining a sense of normalcy, everything goes sideways again.
Nico is attacked by a monster within camp boundaries, and Hades has gone missing. Then the Oracle speaks another prophecy.
One where Nico is the bad guy.
To protect himself, and camp, Nico flees once again, leaving behind his family, friends, and everything familiar for the twisty, crime-ridden streets of Gotham City.
Now, feeling more alone than ever, Nico has to keep his nose clean and try and discover the meaning behind this newest chain of catastrophic events. But trouble seems to follow the son of Hades, and soon he's faced with a new challenge- family.
As Nico tries to juggle hiding his own demigod identity from five of the world's best detectives, and discovering the secret behind their own late-night disappearances, the prophecy begins unwinding around him, sending him into a downwards spiral of disaster and discovery.
