Some use spells and some use taunts. From the Burrow to the upper east side, to Long Island Sound and to Hogwarts School of Witchcraft and Wizardry, Percy Jackson and Harry Potter work together to save their friends, and a few old enemies, living and non-living alike.

Athena said Loyalty will kill him. Loyalty will kill. Maelstrom will destroy. Mystique will torture. He is Perseus, the worst of them all. ----/----/----/----/ His name was Percy Jackson. He was loyal. He was brave. He was powerful. He was betrayed. He was the hero of Olympus. Now, he's Perseus, or sometimes Mystique, or sometimes Maelstrom. He's still loyal. He's definitely still brave. He's very powerful. But he's not the hero of Olympus. Not anymore. I do not own PJO or HOO characters Rick Riordan does. (Warning:I started this when I was 12)

The gods have Percy and Nico help the world that is unknown to demigods. The Wizarding World. Percy is changed into his fifteen year old self so he can fit in, and him and Nico are sent to help stop the war against Voldemort before it even starts. (This takes place after the Giant War and during Harry Potter's fourth year at Hogwarts. You really shouldn't read this if you don't like Percico.) *Art by Viria and cover made on Moldiv app*

All is as it should be. Percy Jackson and Annabeth Chase can finally relax after Gaea has returned to her slumber. Both are alive and excited for their future. But what will happen to their plan of college in New Rome when two meddling goddesses interfere once again? This time it's only a job for the Dynamic Duo. The rest of the Seven have earned their peace, but apparently Percy and Annabeth have not. They find out that not only are Greek and Roman gods real, but another myth is not such a fable. Their next journey will take them to Europe--to the Hogwarts School of Witchcraft and Wizardry. Harry Potter and his friends have finally beaten the Dark Lord. Voldemort is gone and all they want is a normal, uneventful year. Returning to pass their seventh year of magical studies, the Golden Trio finds that their troubles are far from over. Two new students join the misfits of Hogwarts and Harry, Ron, and Hermione do what they do best-dig deep to uncover the skeletons in Percy and Annabeth's closet. Little do the wizards know that the demigods are already on to them, and doing everything in their power to protect their secret. What will happen when all of the cards are on the table? Will they put aside their differences, trust each other, and work together? Or will the world witness a monumental battle between the Golden Trio and the two-time Saviors of Olympus?

Sally died protecting her nephew Harry Potter. Lilly and James Pottor come back home to see her dead and Harry crying. But they notice something else is wrong. Their nephew Percy is gone. All rights go to Rick Riordan and JK Rowling So in this story there is going to be a lot of people who aren't dead. There's Snape, Sirius, Lupin, Tonks, Lilly and James (of course!). Also Fred not going to be dead because separating the Weasley twins is like separating the Stolls! Blackjack and Percy are going to seem more close in this. I've only seen the movies to Harry Potter so sorry for incorrect information! Just tell me and I'll try to fix it!

A/N: I do not own anything except for the things I made, all belongs to Rick Riordan. I know, I know. It's not the most original story. But...You know what? I'll do the disclaimer later. For now, let's get on to the synopsis, shall we? We shall. ~~ People will use you over and over again to their fulfilment. They'll play with you until you're beaten to the bone. Until you're not shining anymore and they throw you away. Well, in my case it's the demigods and the Gods. Look, I didn't ask for any of this. I had accepted anything that came my way before, but don't I get my own happy ending? All I wanted was to live peacefully with my girlfriend, Annabeth Chase who I would do anything for, and my friends. We deserve at least that. So why is it as soon as he comes in everything was taken away from me? What did I do? What did Timothy Leon ever do to have the right to take everything that I have? He didn't save the world. I did. He didn't go to a long dangerous quest alone just for the sake of his friends to finally have a happy life. I did. So, I left. Thus, the start of my new life free from the Gods and their controlling ways. I was finally where I belong but now, I have to go back. Well, it was a matter of time anyway. Sooner or later, you'll have to face the past and unfortunately, my time has come.

(This is the second book in the assassin called Cedmi series) His friends know quite a lot about him. Yet the one thing he never really talked about, were his assassin years when he ran around the universe killing off rich jerks. Percy hoped things would stay that way. That no one would know some things he wanted to stay hidden. Yet, when one person walks right back into his life with a smirk on her face, everything he hoped for was going to be ruined. Because he knew Keneya could not keep a secret even if you paid her a million dollars. And with the war with Void going and the Moon Souls joining Void's side, everything is about to get more complicated. Cause there are things in Percy's past, that he best take to his own grave. For the good of everyone. The question is; will he be able to kill Keneya before she spills out everything about their past? * * * Keneya frowned, but then her eyes widened with an idea. "I'm coming with you, then," she said. "You're what now?" Cedmi asked in disbelief. "Well, I'm tagging along with you," she said. "I'll be like a companion." "Keneya, really, I don't need a-" "I don't give a damn, if you need one or not," she said. "I'm gonna stay with you until I pay my debt somehow or I die, full stop." He stared at her with wide eyes under his hood, before smirking. "There's only one thing you have to do first, though and it might take you a while," he said coming closer to her. Keneya looked up at his cloaked face. "What?" she whispered, since he was so close to her he could hear it perfectly. Cedmi leaned down slightly next to her right ear. "Catch me," he told her quietly with amusement in his voice. And just like that; he was gone. Keneya smirked widely. "I do love a good chase," she said and used her teleportation watch to disappear too. * * * I do not own Percy Jackson and the Olympians or the Heroes of Olympus.

She was a goddess bound by an oath. He was time incarnate - a weapon born from a war the gods swore to forget. Artemis never meant to love. Percy was never meant to exist. But when prophecy fractures and Olympus turns on its own, duty becomes desire - and desire may unmake them both. A mythic enemies-to-lovers romance where time bends, oaths break, and even gods bleed.
