Percy Jackson has always been different.  Even by demigod standards.  

He had normal demigod problems...dyslexia, ADHD, and monsters.  

He had normal problems.  Bad grades, getting into trouble at school, that kind of stuff.

But he was also the son of Poseidon, the subject of two Great Prophecies, the Hero and Savior of Olympus, one of the only living beings...gods included, to survive Tartarus, one of the only demigods to bathe in the Styx, and one of the only beings that ever held the sky.  All that makes him different.

But now, he was about to delve further into abnormality, when he finds out he has another evil grandfather.  This time it isn't an evil, immortal, all powerful Titan Lord that likes eating his kids...just a powerful, evil noseless creep with a freakish, yet hilarious name that somehow makes people flinch.

And now, Perseus Jackson, the son of Poseidon, is about to go on his strangest adventure yet...going to Hogwarts School of Magic.  Yet another tragically hilarious name.


(Look, I know there are a lot of these and it's pretty classic, cliche, and slightly overused, but I promise you readers that this story does not fit into that mold.  Give it a shot, and see how it goes.  But if anyone steals my plot...I'll feed you to my pet Hellhound :). )

Percy Jackson is dead. That must be hard for you to hear, huh? After all, you knew him better than I did. Maybe this story would have gone a lot differently if he was around. But he wasn't. It's the year 2030. After all the mythical wars and battles the universe was beginning to calm down. But Percy Jackson is dead now, so there is no one left to keep it on order As a demigod life is kind of hard. Killing weird stuff that want to kill you for the fun if it, or because they feel slightly peckish? To that I say, such is life. My name is Xylee Cross; Daughter of Poseidon. I'm now his only demigod child. The expectations for me are pretty high being the half sister of THE Percy Jackson. Ah, yes, another cliche story about a daughter of Poseidon. You may ask "Xylee, why can't you be original?". Well, my birth had nothing to do with originality. It had to do with the fact that sometimes gods have children, and those children end up with a lot of work, many messes to clean and a lot of mistakes that probably won't be dealt with the easy way. Sounds fun, right? This is the one where I receive a prophesy that leads to a quest. That quest leads to a lot of confusion and irritation, but in the long run it leads to the world being saved. -------------------------------------------------------------------------------------------- Okay, so most of the characters are mine. This idea of this book was inspired by the amazing Rick Riordan. Please don't take this idea or this story or I swear I will hurt you.

❝Uh, mom, why are Gandalf and company lounging in our living room?❞ Percy Jackson is about as normal as it gets. Or so he wishes. But instead, he's the son of the god of the sea, has saved the world a grand total of two times, and now has a second evil grandfather? You'd think one was bad, but nope there's another one. Did I mention the wizards? Harry Potter is frustrated. Dementors coming after him, the so called Order of the Phoenix, who won't tell Harry anything, except for one thing. Just one thing. That the grandson of Lord Voldemort himself is going to live with them? [discontinued]

The Prophecy That Changed the World by Marichfrlife
15 parts Ongoing
Percy Jackson is an average kid. He's bullied in school, has no intrest in learning math, and hates geometry. He's dyslexic and has ADHD, but his mom says thats normal, and she's always right. Just because he can read the weirld language his mythology teacher shows on the board doesnt mean he's weird, and its not like he told anyone about it. So yeah, he just a normal, average person...until he's transported back in time. Now he's fighting monsters he never thought he'd fight in Ancient Greece, because the gods and godesses sent him on a quest that could destroy the world if he fails. No pressure, but at least Percy's not the only one stuck saving the world, his emo neighbor Nico and "responsible" friend Jason are stuck with him too. Percy just wishes he could sleep properly again, and who is the cool blond girl that transfered to his school? Why does she look so familiar? Sorry in advance for bad gramar, this is my first fanfiction about an aready existing topic and I hope people like it. (Future author here, I just relized the first time I published this I spelled prophecy in the title wrong, sorry.)

37 parts Complete
A few years after the war with Gaea, the demigods face another series of problems. A new wave of maleficence headed by someone only known as the "Mad Usurper" is coming for the gods and demigods. In addition to that, their personal problems are also in the way. Will the heroes be able to resolve their problems and stop the Mad Usurper? How will the succeeding events affect Olympus and their fellow demigods? All persons, monsters, gods or demigods living or dead in this fanfic is purely fictitious...or are they? Any event/s about to happen or happened before is/are purely coincidental. This is a fanfic of PJO and Heroes of Olympus in case you're wondering. FOREWORD: The comment section is always open if there are suggestions about the writing style, threats, bashing, reactions, etc. My co-editors are Keira_Viresse and enigmaticyouniverse. Take time to read their amazing works too. Enjoy reading!

All her life, she had loved. She embraced the love she received and shared it with the world who seemed to lack them. Loving has always been the one thing no one could take away from her. But loving was the one thing that could take her away from the world. Loving came with a price- undeniable loyalty. Personal loyalty. A fatal flaw that would lead to her demise. A flaw that even the strongest heroes could not recover from. A flaw that they could not change. Because with loyalty, comes the pain and suffering. With the second war brewing within the shadows of the world, comes the hardships and suffering. It was strange how ignorant humanity could be. The little things that people overlook, the ignorance they have that would ultimately lead to their demise. The pesky little problem within the Wizarding World was no match for a demigod- much less the daughter of Hades. But when two worlds collide- only then, did she wish she never overlooked the little things. That was her first mistake. How do you face death and darkness all your life and not succumb to it? But maybe, just maybe, it was time to give up. ▶︎ •၊၊||၊|။||||။‌‌‌‌‌၊|၊၊||၊|။||||။‌‌‌‌‌ • 00:23 ----- 𝗹𝗶𝘁𝘁𝗹𝗲 𝗳𝗿𝗲𝗮𝗸, harry styles ❛ somehow you've become some paranoia, but your gift is wasted on me. ❜ ⋆˖⁺‧₊☽◯☾₊‧⁺˖⋆ HARRY POTTER - The Order of the Phoenix HEROES OF OLYMPUS -
