Summary
The war is over, and the quiet life is a welcome change for Percy and Annabeth. However, fate has a way of throwing a wrench in their plans- this time through an owl that delivers the letter with a plea of help in a magical war. Crash-landing in a strange world amidst a terrorist attack, they must navigate a hidden world of magic they don't understand to protect a 14-year-old Harry Potter—a boy who, according to their sole piece of intelligence, is already dead.
Their mission is a paradox, their only intel is a lie, and they are utterly alone. They must unravel the mystery of their summons before a ruthlessly efficient Lord Voldemort can begin a secret, parallel war with a divine power that could unmake reality itself.

Half-blooded Half Blood Harry by Jo_mama

Summary
Harry Potter is a half blood! In both a wizarding sense and a godly sense. So he's sent to Camp Half-Blood after his second year of Hogwarts. Find out who his godly parent is and see how this changes the stories of Harry Potter and Percy Jackson. For now, the goal is to cover the story of the first Percy Jackson book, and if I enjoy writing this, I'll make a part two. I'm not sure how much this will diverge from The Lightning Thief, but if I write further than that, there will be some larger changes.
Inspired by Harry Potter & the Olympians: Tides of War, by VinCredable. It hasn't updated in a while, so I wanted to try write something similar myself.

Summary
It was too much to ask for a single, uneventful year, wasn't it?
Oh well, Percy didn't have much plans anyway. His plans were staying in his mom's apartment, taking Estelle to school and picking her up. Maybe getting a part-time job. He and Annabeth were taking a gap year before maybe going to New Rome for college. They weren't sure yet, but they'd figure it out.
Now they just had to help save the mysterious magical wizarding world.
Hooray.

Summary
But so thus, the Angel of Death was literally just going to be how demigods were for the gods. Which, fair, he’d chosen to do this, and to be claimed as one of Death’s children, however not literally, would be an honour.
The other kids however wouldn’t have had a choice in that, having just been born that way, so it sucked for them.
Man, the gods could at least be more grateful towards their children.
He supposed though, with the small lifespan of a human, that it would do nothing but hurt to get close to them. But then what would even be the point of creating them? Well, probably because otherwise they didn’t have any believers and would fade, but man, no thanks for continuously defeating their enemies. That sucked.
(he tried not to think about the parallels)
Despite that, and many of his very pissed off thoughts, he was temporarily being lent over to Hades to get his children for him and bring them to the Underworld.
And they also weren’t at camp. Yay.
---
OR, Harry, basically Death (Thanatos)'s adopted kid, gets lent out to Hades for a task.
To get his kids...And he may or may not run into a certain pair on a quest.
