The Quest (PJ & HP crossover)

This story is from my old account ShadowTori. I wanted a clean start on everything. But I did enjoy writing this crossover and since many of you liked it, here is the new and improved rewritten crossover. It'll have the same plot, but it'll be better. And yes, it will be a series. Hope you enjoy:)

Also side-not. It's been a while since I've read the books, or written anything like this. So if I make a book error. Let me know. Thank you.

(Based after Trials of Apollo book 1 and Magnus Chase book 2) I'm diving straight into the story.
******************

Things are going down in the demigod world.

Camp Half-Blood has been somewhat neutral, minus the fact that Apollo is now human for the time being. Camp Jupiter is still friends with them, sending demigods back and forth. The Greek camp has been consorting with the them trying to figure out who the mortals are in the company that helped finance Luke's side in the war against Kronos and that has been taking halfbloods in New York. It's still a dangerous mystery.

Sadie and Carter haven't been seen or heard from since their last meeting with Percy and Annabeth.

And nobody knows what Annabeth is doing. All she said before she left was that she was headed toward Boston for some family emergency.

So yeah, things have been tense. With Percy Jackson using all his time for college and summer almost over, no one can tell what will happen this year.

But it won't be peaceful. It never is.

Nico di Angelo has finally decided to consider Camp Half-Blood somewhat of a home. He was actually making future plans involving traveling and helping the other camp. Things were -not the best but- actually not that bad.

So of course, what would happen except Hades showing up out of nowhere and basically forcing him to help out in a secret quest across the world.

A place called Hogwarts filled with magical things. An evil wizard with a strange name. And another black haired, green-eyed kid hero.

Why not?
