Hey everyone,
SORRY! SORRY! SORRY! SORRY! I was checking the preview to this story and suddenly noticed how it was missing a chapter, so I re-uploaded all of the existing chapters plus the missing chapter and decided to repost the entire thing. I am really, really, really sorry that it took me this long to realize it, but it's all fixed up now.
Wow! Blood of Olympus came out yesterday and I spent till midnight reading all of it. I am a little disappointed in the open ending and I just want to warn those that haven't read BoO to NOT READ THIS, but the open ending actually made me want to write this all out and made me so relieved as this idea has been stuck for a while.
I have actually been wanting to write a HP-PJ crossover since House of Hades, yet I didn't know what would happen in the HoO final battle, so I kept the ending plot to myself and vowed to work where I could. Personally, I was hoping for a better ending to the whole 'Nico Reveals His Secret To Jason' thing, but oh well.
Anyway, I just want to let all of you faithful readers know a few things: 1. THIS WILL HAVE MALEXMALE RELATIONSHIPS! I got a hater once on my ACPtF story that apparently the warning wasn't detailed enough, so I hope this will be better for whoever is against MalexMale relationships and whatnot.
Second, this story plays out in 1995! I know from the Camp Halfblood Wiki site that Percy is actually born in 1993 and that the whole Lightning Thief starts out in 2004 and whatnot, but it's for the sake of the HP Universe and while there are more PJ books, does this story mainly follow Harry's growth, so there.
Finally, will there be characters that stay permanently and characters that leave whenever they so need to or that just appear whenever the Fates believe it is time or of essence for them to join in. A few of these characters are: Kingsley Shacklebolt (he will later stay permanently, but that won't be until the second book) and the Olympian Gods.
Okay, I think that's all,

Prologue
An Endless Flight

Leo's POV

I don't know what could be wrong, but according to Festus, the mechanical dragon I was able to build after finding a legendary Bunker created by the Olympian God Hephaestus, was the journey he and I took to get to the Island Ogygia only a day flight, which took from the late afternoon of August 1st to August the Second.
Yet this journey that I and my Girlfriend, Calypso, have been undergoing now – that is apparently through a thick blanket of mist through which even the lights of Festus' eyes can barely see a thing – is already three days underway and by now the both of us are wondering whether or not it would be wise to turn around.
I had already tried doing so, yet Festus had been determined that, eventually, his glowing look would pierce through this strange blanket, a blanket he had told me we hadn't encountered while he had fled myself and him out of Camp Halfblood, away from the exploding Gaia and over to wherever he could try and cure me.
The cure – also known as physician's cure – is still festering and burning through my blood from where Festus had injected it into my stream through my right forearm and I can't help but wonder if this endless journey through the mist is the cause, whether or not Calypso and I ended up in a whole new stage of In-Between Life.

I know my beautiful girlfriend is anxious as she just isn't as comfortable upon the metallic neck of a steel made-dragon as I am, yet the amazing girl has yet to complain even a single time or even ask me if it wouldn't be better for us to turn around, while I know in my gut that by now the girl must be dearly missing her Island.
It had been a place she had been banned to a thousand years ago by the Gods of Olympus after they won their war against the Titans, a war in which Calypso apparently supported the Titans, something I just cannot blame her for as her father was actually Atlas, the Mighty Titan that – to this day – holds up the Sky for all to see.

I then shudder, as the reminder of titans reminds me also of Gaia, a fierce Earth Titan that wanted to destroy everything – and I mean everything – that was build on her body and who had to take on some sort of Human form before – through help of my friends and Festus – I had been able to destroy her conscious and end her reign of revenge.
The whole attack on Gaia had cost me my life five days ago, yet I had prepared for it, having known – and even felt – that it would come down to my death and so I had tricked my friends, made it look as if my Charm-speaking Friend, Piper McLean, had the Physician's cure, while I had actually made it part of Festus' internal machinery.
This decision had saved my life, but because I had actually died, had I been able to get to Ogygia, where I had met Calypso, who had actually been waiting for me while she had, when I left her island the first time, told me that no man could find Ogygia twice and it had taken us only ten minutes to get off the Island again after that.

Now we've been flying for five days straight and while we had each at certain times felt drowsy and even fallen asleep at times, had neither of us fallen asleep at the same time, had neither of us needed to make sure the other wouldn't fall off in their sleep and had neither of us felt any need to either eat or drink since we entered the mist.
All of this makes me confused and worried, mostly because the mist seems to have several effects on all of us. It makes me incapable of seeing anything other than Festus, Calypso and the headlights that Festus shines from his eyes, makes Calypso feel like returning to her island and makes Festus ignorant to my orders of turning around.
"This has to be Fate, Leo. It just has to be proof that the Gods can't be trusted. They promised Percy that they would free me and that was – even I know that – months ago. They told Percy some story just to keep him entertained because he refused their offer and now you and I are stuck here, not on my Island, but in some cloud of mist."
Calypso says angrily as she looks around her at the mist, a mist that makes it impossible to see either sky or land, either water of the ocean or even a tree sticking out of the ground and that even makes it so that Festus' headlights only shine for 500 miles ahead, while the power of his light should be able to reach 4 to 5 kilometers easily.

I know it's risky to agree with my girlfriend when we are clearly in Godlike territory, yet my heart is telling me that somehow, Calypso isn't fully correct and I know it's not just because of the amazing way the Gods came to our help when Gaia had woken and the Titans had surrounded us at the Acropolis in Athens, Greece.
"I'm – not entirely sure it really is the Gods, Sunshine." I say hesitantly and not because of where we are and while I can feel her angry glare in the back of my neck, do I say: "This definitely has a Divine touch to it, but – I don't know – something tells me there are forces even stronger than the Olympian Gods at work here."
This worries my girlfriend and sets her thinking at the same time as she asks: "Is it – father? Could he – could he have escaped his prison?" But I shake my head again, understanding why Calypso would be most worried about her father escaping and say: "No, not quite the titans either. I just – I just can't place it, really."
And while my girlfriend lies one hand, with her fingers curled, against her worrying lips and uses the other to grab the back of my restored t-shirt, while Festus just keeps flying straight ahead no matter what I try to tell him and while I personally try to see further than where his headlights shine, do I have no idea how right I really am.

Harry's POV

The last few days have been nothing short of hectic and I feel kind of overwhelmed with all that has happened in such a short time, even if there had been a three-day break in-between all the crazy things that have happened, one that did absolutely nothing to settle the nerves that have been festering inside me for the last month.
Just four days ago were my cousin and I attacked by two creatures that no one should ever want to witness, let alone get attacked by; Dementors. Dudley and I had both almost lost our souls, yet I had – in the end – been able to do what almost made me lose my soul in the first place; cast a Patronus spell that had saved us both.
After this had I discovered that I was being constantly watched by people – some of which I know, others I don't – had I received several letters, none of which had congratulated me on my success in not getting my soul sucked out and had I almost been expelled, before being put on Probation and being told I would have a Hearing.

This had also been the night where my Uncle – Vernon Dursley – had tried kicking me out because of the Dementor Attack, something Dudley blamed me for because as a Muggle he had been unable to see the Dementors, yet a strange Howler sent to my Aunt Petunia had made the woman decide that I was to stay.
I had been grounded to my room, bar to unleash my needs every now and then, and while I had been fed properly according to Dudley's new diet, had my main concern been something futile, to get information out of my aunt as I have no idea why a Magic-Hater like herself would be in contact with Howler writers or wizards.
Then, three days later, yesterday had my aunt and uncle been invited to something I had doubted could even be real as the name of the event sounded just downright fake and had proven how biased, blind, vain and dumb my relatives could really be, before a whole group of witches and wizards had come to pick me up.

I had not been happy with the sudden change of no information whatsoever to suddenly being picked up and being expected to just accept all of it, however, because the adults had left me alone with my friends and because of my hormones, had I unleashed my anger at the wrong people – something I didn't realize until too late.
I had apologized to my friends and had done my absolute best to make sure the adults would do the one thing I had been demanding of them for over a month, yet it had been only one adult that had actually believed in my rights concerning this; my godfather, who is supposedly on the run for having betrayed me when I was one year old.
Sirius had done his best to get me the chance he and the others knew I had been dying for, yet his rival had been as stubborn as he is, even if she had not seen the error of her ways afterwards and had even made a comment that still makes my blood boil almost 24 hours later. Mrs. Weasley had ultimately been defeated, however.
I had received some of the information I had been craving, yet the information was so vague and open and easily interpreted in so many ways that right now I have even more questions, different ones but still more and I can't help but resent those idiots in the Order of the Phoenix for thinking I can't handle a bit more.

After Mrs. Weasley had ended the stream of information short, shorter than would have been smart as far as I'm concerned, had the woman escorted myself, my friends Ron and Hermione and Ron's brothers Fred and George up to our rooms, the twins quickly coming to our room to discuss what we had learned.
The woman, however, had intercepted our conversation before we could really come to some clear answers and the doubt and insecurity had led me to having some really strange dreams, along with the usual that has been haunting me for the last month or so, before Ron had woke me up and we had all started cleaning the house.
We had gone to the Drawing Room, where Pixies had apparently nestled themselves in one of the curtains and while I wonder how the woman can be as hypocritical as to not allow us into the Order but still let us fight against the many creatures infested in a House of Dark Wizards, is there still one person that understands me.

Sirius had taken me apart somewhere during the cleaning and had shown me what the Ancient House of Black was all about. The man was so obviously not happy about being here, I couldn't help but wonder how many people would have to be unhappy with Dumbledore's decisions before someone would shove that displeasure in the man's face.
Sirius had then shown me some of the good members of the Black House, yet had barely even spoken a word about them – probably because he himself had barely been taught a thing about these people. However, the dark ones had a bit of History Sirius had unwillingly shared with me and in the end he had taken me back for lunch.
I really can't help but appreciate all the man does to make me feel better, even if he did bring up the Hearing I would rather forget and if he avoided my question about whether or not I could live here if I didn't get cleared, yet I know that it's just because the man doesn't want me to live in the same place he grew up in.

He and I are only a few steps apart as we move to the other side of the room, where the four youngest Weasley Siblings are all eating sandwiches along with my best friend Hermione and Mrs. Weasley herself, but before I can even so much as turn around and take a few steps, do I feel an unpleasantly familiar magic settling in.
A pull behind my navel and a bright light appear at the same time, the light surrounding me as quickly as the pull takes me away and the only thing I can do before being plummeted into the swirling world of Portkey Travel is reach my hand out to my godfather, see him turn around at seeing the light and shouting: "SIRIUS!"
But even my shout isn't all heard before I am whisked away and the first thing I do upon landing, is making sure I don't fall too hard or land in any way that can make whoever activated that Portkey take advantage of me as I roll around on my side, grab my wand from my pocket and end up in a crouch with my free hand on my knee.
I look around, my other hand firmly around my wand and my mind going like absolutely crazy as I think of all the spells I studied to fight off whatever could be in the Maze of the Third Task, something I didn't even consider when Voldemort had taken me from Hogwarts, revived his body and challenged me to a duel.

I quickly shake my head, knowing now is just not the time to get sucked into that horrifying memory and look around, but all I can see is a circular room with forest green walls, oak brown doors and an amazing set of comfortable couches, chairs and sofas, all positioned near a beautiful grate and with a glass table next to the grate.
I aim my wand at the surroundings of the grate and cast all kinds of spells – spells I studied without my friends knowing and that I learned from several library books that Madame Pince, the Hogwarts Librarian, will never miss because Dobby – my House-Elf Friend – sends them back once I am done reading every day again.
The House-Elf had been ordered by Dumbledore not to seek me out or to tell me anything he didn't find adequate for me to know, yet the little bugger had been only too happy to let me study as he said it was just for school, not anything that I would have to endanger myself with, even if the spellbooks were for defensive purposes only.
Feeling ever so grateful for the spells I silently learned, do I try them out the best I can and because this is my first time trying it, do I feel slightly unsure when my Human Detection Spell comes out empty, proving to me that there is no one else in the room or behind any of the oak wooden doors around me.

I stand up, keeping my eyes on all of the doors one at a time, my eyes going in endless circles, while I keep my inner focus on my target, the grate, and when I arrive there, does a magic I had not expected activate, one that makes me raise my wand at the ceiling, even if the whole room is dome shaped, as a powerful voice speaks:

"One by One, the Readers Shall Arise.
For one Chapter Read, a new Ally shall Appear.
All seventeen Books must be Read.
Only then may Fate be Finalized for Good.
Only through Reading Can There be Peace.
Only through Reading Can Families Unite.
Only through Peace Can Olympus Remember.
For the Forgotten Ones Deserve to Live."

This shocks me as I had not expected to be witness to yet another prophesy and I can't help but think: "At least this one speaks of safety and life instead of the return of a Murderer." And I shudder as the voice sounded nothing like the disturbed voice of my Divinations Teacher during my Third Year Finals, when she spoke a Prophesy.
Then my curiosity gets the better of me and I wonder: "Didn't she mention something about books?" And, as if covered by a Notice-Me-Not charm that drops at my words, do I see seventeen books, all of them hard-covered and with beautiful pictures on each of them appear on the glass table, in 1 row of seven and two of five.
I look at the books and notice that one of the rows has a note on top that, after casting several more detection spells on it, I pick up and read: "Start at the top." Making me look back at the first pile, which consists of seven books and I can't help but wonder: "Who are these about anyway?" And I read the titles.

"Harry Potter and – oh, great, they're about me. Wait, seven books about my five years at Hogwarts? There is more going on than just some maniac trying to drive me up the wall here. What are those other books titled anyway? Percy Jackson and the Lightning Thief? The Heroes of Olympus – The Lost Hero?"
Feeling like these titles just won't bring me anywhere at all – even if the name Percy Jackson rings a familiar bell I just can't place – do I sigh, remembering the prophesy one sentence at a time and I ask: "So one person will arrive when I read the first chapter, huh?" And I shrug, deciding my only option is to comply with the words of Fate.

Okay, sue me!
So that went WAY better than I expected, but I have been hellishly busy with so many amazing stories so far that – well, my talent as a Fan-Writer has just really grown over the years I have been on this site and I really want to prove that with this story – even if not everyone is a real CR story fan or PJ, HoO or HP fan.
Okay, a few more things: I am not ENTIRELY aware of who is who again when it comes to PJ-HoO and I might confuse someone with another every now and then, but I do constantly TRY to check the person I am writing about and what their history, their parentage and powers are before I write anything about them.
Also, I plan to make some of the HP people be Demigods, but I have a few questions as I am not entirely sure who should and who shouldn't be Demigod. I am thinking of making some Weasley kids Demigods, but not all of them – definitely not Ron, Ginny or Percy. Harry, however, is a Demigod MUST, so yeah, that's my problem.
That is all I can promise,
