AN: This is my first story. I am trying to write and update the chapters as quick as I can, but no promises. There will be an irregular posting schedule. I am British, and Percy is American, so I apologise for any mistakes. Will be cross-posted on and ao3. Hope you enjoy!

Disclaimer: I do not own Percy Jackson.

The Fates, the Nørns, and Shai, the Egyptian god of Fate, were working together to create a magical place outside of time and space. It needed many rooms, and would summon anything it was asked to. When they finished, they looked at each other, and clapped their hands sharply. With a flash of light, they disappeared, and 99 demigods, 73 gods, 23 mortals, 14 magicians, 5 satyrs, 2 elves, 2 dwarves, a cloud nymph, a dryad, and a centaur arrived. After two seconds of stunned silence, a wave of noise erupted from the group. Of course, as everyone was shouting, no-one was heard, so there was no point in shouting anyway, but that didn't occur to the gods. In the midst of the chaos, Hestia stood patiently, used to her dysfunctional family. Then, a note fluttered down from the ceiling and landed in front of her. Noticing it was addressed to her, she quickly read it. "Silence!" roared the eldest goddess, flames burning all around her. Since she was well known as the calm one, everyone was too shocked to disobey.

Once everyone was quiet, Hestia spoke, "Everyone sit down."

They did so.

"The Fates themselves have brought us here. They sent me a note. Do not try to defy them. Do not try to harm anyone. It will not work. We are outside of time and space here, and as such can pause in our usual duties. We will be receiving another guest shortly, who will explain further." She sat down, and seconds later, there was another flash. This time, it transported only one person. A girl, looking to be in her early teens, with shoulder length dark hair, and a rucksack on her back. The girl looked at all the gathered people, and spoke.

"Hi. My name's Rose Dearly. I've been sent from another universe. In my universe, the myths were just that: myths. Stories passed on through the generations. Made up facts, to explain that which was unknown. Now, in the 21st century, stories are being told about the myths. But each one becomes real. Another universe, unknown to all. As the ones in charge of each universe, each trio of Fates whose universe has been on the brink of destruction at least ten times in five years are informed. Each trio of Fates informed are allowed to choose one person who has read their book, or books. One person who is then tasked with helping that universe to stay on track. To change their Fate. To not be destroyed. I have been chosen to save this universe."

"How do you plan to do that?"

"By everyone sitting down together and reading the books I've bought with me. So far, the author, Rick Riordan, is part way through the fifth series. When the next book is published, it will arrive here for us. We're going to be reading them chronologically, starting with the series 'Percy Jackson and the Olympians', then carrying on with 'Heroes of Olympus', then 'Kane Chronicles', 'Demigods and Magicians', 'Magnus Chase and the Gods of Asgard' and 'Trials of Apollo'. The last two take place at the same time, and you'll hear each referenced in the other."

Again uproar. Percy, Magnus, and the Kanes were surprised that someone had named a series of books after them. Apollo was worried that he seemed to have some troubling times ahead. He didn't like the sound of these trials. Everyone else was worried about how Rose had said their universe had been in deadly peril ten times in five years.

Once it had calmed down a little, Rose spoke again, "Spaced out chronologically between the books we'll read the short stories in the extra books Rick published about the series. Between 'Heroes of Olympus' and 'Kane Chronicles', we're going to be reading 'Percy Jackson and the Greek Heroes'. It is the sequel to 'Percy Jackson and the Greek Gods', but we're not reading that, because it's not necessary to make the future better, and gives the gods even more reasons to kill Percy for his rudeness, although they can't do so here.

"Also, there are people from several different timelines here. If you change the future, it will create a branch off the main timeline, as you cannot change the past, and therefore, cannot influence what as already happened, even if you have not lived through it yet. Sorry, people from 2011. However, you will notice the dead among you. For the duration of this reading, they will be back in their normal bodies, and you can interact with them as if they were still alive.

"The Fates are strict. As well as saving their universe, this is a massive form of entertainment for them, and they're not going to spoil it. However, other than two rules, they're not going to interfere, either. The rules are, first, no spoilers, but if someone from 2005 wants to know if they're dead in 2011, come and see me. Second, no causing anyone harm that cannot be completely cured within half an hour. Yes, this includes godly healing. You physically cannot break these rules, if you wish to try, be my guest. It won't work.

"Another thing, when you introduce yourself, don't say any of your titles, just say what pantheon you are from, and what you are, eg. Greek demigod, or Egyptian magician. Gods, you have to guess who your children or hosts are. If you guess correctly, they will then introduce themselves with all their titles. And Percy? All your titles, without complaint, otherwise I'll get Thalia and Nico to say them for you." Thalia and Nico grinned. Percy nodded rapidly. Thalia and Nico looked disappointed. "I know there are people here from the past that those from the future already have feelings for, either positive or negative. Do not blame anyone for something they haven't done yet, even if you know they did it in your past. I think that's it. Shall we start with the introductions?"

They went round the room each of them introducing themselves as they had been told.

"Excellent! Now, let's start reading. Who wants to go first?"
