When Percy Jackson is mistaken for Harry Potter by a group of Death Eaters while on vacation with Annabeth in Europe, chaos will ensue as the Order tries to set the couple free and Camp Half-Blood tries to find their missing leaders. The plot starts after the intro chapters. It's set just after the Giant War and in between the Order of the Phoenix and the Half-Blood Prince.

Harry Potter has a younger brother who survived Voldemort too. Then, before anyone could find the second son of Lily and James Potter, he disappeared, never to be seen again by the Wizarding World. Until, almost, fourteen years later. Dumbledore and Sirius collect him from Camp Half-Blood and they show him his true identity. His name? Percy Jackson. T for A LOT of language.

Sequel to my version of The Blood of Olympus. Recovery fic. Lots of fluff, but plenty of angst and action as well. Friendship, family, and love are definite, solid themes. Happy Reading!

A period of Darkness has befallen Middle Earth. Sauron has risen once again, intending to destroy the Free Peoples of Middle Earth and set himself up as supreme Lord and Ruler; against his immense army there is no hope. With these insurmountable odds, Olympus is forced to send aid, and Percy wakes up in Middle Earth with only one objective: topple the Dark Lord from his throne.

No, Seriously. Idiots. Which idiot's idea was it to raise Lucifer anyway? They should have at least checked if he was home before they charged in guns blazing! But nooo, they didn't even care. He can't ALWAYS appear at their beck and call, you know. He has a LIFE. First in the stupid series.

Percy murders demigods in cold blood at the end of the second titan war and is banished to Tartarus for eternity. With the Prophecy of Seven coming to pass, he is released to fight in the new war. Romans and Greeks collide and everyone has one question on their minds: which side is Percy really fighting for?

Sally Jackson's mother died with a secret; She used to be Queen Susan the Gentle. Percy never knew Narnia or Aslan, he barely remembers Susan's maiden name. So when he, Annabeth, Jason, Piper, Frank, Hazel, Nico, and Will get sent to a land of eternal snow, meeting his dead grandmother isn't Percy's only surprise.

Rachel's newfound family is coming to stay for the rest of the summer following the Second Titan War. Though she has her own secrets to hide, she find's that there may be more to the red headed family than meets the eye.

But will he let her in? And will their relationship prevail with Rachel, who seems to know everything before it happens, and Luke, who still hasn't gotten over his break up with Annabeth? T for abuse

Annabeth couldn't believe it. She'd just gotten Percy back from the Romans and now some creepy dudes in white coats show up and take him! Percy, on the other hand, was confused. He'd woken up in a strange place, with strange kids, and strange feathery things growing out of his back. Why wasn't he at Camp Half-Blood?

He's fought legions of monsters, turned down immortality (twice), saved Olympus more times than he can count on his hands, and survived Tartarus. Peace seems in sight. But when a foe older than Gaea arises, Percy Jackson faces him, and finds he may not be strong enough. Banished from Camp Halfblood by the gods, Percy and now River must find a way to end Fear...or else. AU.

Perseus Jackson was a strange person, Harry decided. He came from overseas, had the weirdest American accent, spoke strange sayings, had ADHD and dyslexia, and stood up for every kid. He was a Gryffindor, but consorted with Hufflepuffs, Ravenclaws, and even Slytherins. Perseus Jackson was a weird person, Harry Potter decided, but he wouldn't have it any other way.

Takes place after Son of Sobek and Staff of Serapis. Carter and Sadie team up with Percy and Annabeth to take down Setne who is still trying to make himself a god and throw the Greek/Egyptian worlds into chaos.

When Sirius Black escapes Azkaban; Dumbledore has his old centaur friend Chiron send his best demigods to protect Harry Potter. But as these worlds collide, Percy, Harry, and the rest of the group discover a Dangerous Alliance that may destroy not only the mortal world, but the Mythological and Wizarding ones as well.

When Percy and Annabeth fell into Tartarus, they had no clue the horrors in store for them. Three horrible weeks later, they have found the open Doors of Death, miraculously both alive. After the Seven save the world, Percy and Annabeth attempt to heal.

When The Blood of Olympus came out, it really disappointed me. I love Riordan's writing, but this last one felt rushed. He had so much buildup from the other four books, and I just couldn't stand how much of a let-down it was. So I decided to write it how I would've liked it. This is just a fan's opinion, so take it with a grain of salt. ON HIATUS UNTIL FURTHER NOTICE.

After an incident with a monster he knew nothing about, Percy was stuck in Purgatory with all the creatures out hunting for his blood. There, a certain human might be his only hope for getting out of the place. But after the portal, there might be more troubling matters awaiting him out in the wrong world. And the demigod is alone. Season 8 rewrite.

Almost five months after Gaea was defeated, the demigods thought they were safe. But now monster attacks are increasing and a new threat is on the horizon. The former crew of the Argo II must come together again for a new quest-or risk losing everything they fought so hard to save.

Percy and Annabeth both make it to the doors of death, but percy doesn't make it out of the doors in time. Everyone is on edge as Percy tries to survive on his own in Tartarus while the six try to find a way to get him out of there at Camp Half-Blood and manage to kill Gaea... Will Percy make it out alive? Who will be able to help him if he does?

It's been a few months since the fall of Gaea. Percy's been spending his time around camp, hanging out with his girlfriend, and trying to forget some of the not-so-stellar parts of their recent journey. As it turns out, there's one part of the quest he can't forget. Tartarus. Little does he know, Tartarus may have left a bigger impact than a memory. One that may cost him his life.

The gods were keeping their promise, and everything was falling into place. Percy thought things finally seemed to be looking up. Of course, Percy was wrong. Sometimes the past can't stay hidden.

There's a part that's never told about heroes and legends, it's the part that's easiest to hide because everyone so desperately wants to avoid and forget, and Percy knows why. It's the part that no one will talk about in broad daylight, and completely takes over when it's 4:00 am, and you can't sleep. A fic about what happens to our favorite hero, once everything is over.

AU where the team doesn't remember who Percy is, but lets him stay with them anyway. A story of getting to know each other again and remembrance. Set in The Art of Finding Yourself verse, but you can see it as a kind of outtake from The Art of Team Bonding.

When Percy comes down with a cold, he dramatically tells Annabeth that he's 'dying' over an Iris Message. Gossip spreads rapidly on Olympus and Poseidon honestly thinks his son is dying. He will do anything to keep his son safe from Hades' realm. Percy really wishes he had just kept his mouth shut. Sick-fic. Father/son fluff.

… then look again. Persephone Jackson is gone, and Jessica Grace is forced to watch Archimedes Chase try to heal the chasm she left behind her. a genderswitch au set during the time between the Lost Hero and the Son of Neptune.

This is a story of broken minds and broken hearts. Of a demigod who lost everything he had, but still fought. Of a god who had his whole life a lie, but still yearned to live. And of a brilliant inventor who afflicted by nightmares, but still donned his mask.

With the war against Gaea over, the seven, Nico and Thalia barely get a rest before Chiron informs them of the magical world of wizards and witches. Specifically, a boy named Harry Potter, who is entering his 5th year at Hogwarts. Percy's job for an entire year is to keep the Chosen One safe from Voldemort. But the evil wizard seems to know more about Percy than he should. AU

"Piper looked away, trying to block out Percy's anguished cries, tears pooling in her eyes. She had never seen Percy— or anyone for that matter— look so… broken, so scared. Phobos, on the other hand, stood just to her left, grinning like he was watching an amusing movie. A wave of anger hit her. How could anybody be so cruel?" A Percy and Piper friendship story. NOT PERCY/PIPER!

Loyalty. Percy's fatal flaw. Before, it had always worked out. He always managed to save both his friends and the world. But now, he is faced with the ultimate sacrifice. And he just can't find the strength to do it. This fanfic is HoH spoiler FREE.

Colors are beautiful. Colors are deadly. Colors are the world, he muses.

He knew his girlfriend obsessed over Harry Potter too much. But when he wakes in the wizard world, with nothing but Riptide to guide him, will he wish that he'd paid more attention to Annabeth? Will our hero survive at Hogwarts?

(Dark Percy) Percy's life is ruined, now he has nothing left but a vendetta. Now he must deal with an apocalypse, demons, angels and hunters. But the Devil isn't all he has to worry about, something ancient that has been sleeping for eons is waking up and the world stirs. But Percy isn't alone, an old 'friend' is always nearby...
