The gods were on Olympus arguing. They argued and argued and it was so annoying. The primordials themselves had gotten annoyed by their arguing that she decided to show them their future.
They all were shocked when the demigods and Chiron had teleported to Olympus and they were given dirty looks. It was one of the most beautiful things that many would have ever seen.
"Why are you here?!" yelled/asked Zeus, why do you think he is called the god of drama and Dionysus inherited from?
"You didn't summon us?" asked Percy who was the bravest of them.
"We didn't, but then who did?" asked Athena.
To reply to this a book appeared and a note. Athena read:
Dear annoying gods of olympus,
We have heard your arguing for thousands of years and now after your mistakes have been used to punish you, you still dare to argue. We will put an end to this by allowing you to read Jackson made fun of your children.
Thank you, Primordials.
Percy was embarrassed as the title was read: Percy Jackson's Greek heroes.
"You wrote a book?" asked Athena, shocked he could write something.
"Yeah I've written a lot of books in total" said Jackson as though it was very obvious to most of the demigods, gods except Chiron, Annabeth and Nico because they would have obviously helped.
"So what are their names?" asked Athena for a mental note.
"My first series is called Percy Jackson and the Olympians, my other books are short stories and there is my greek gods book this one, I was also one of the authors of Heroes of Olympus" said Percy to which the gods and demigods were in awe.
"Should we start?" asked Percy embarrassed at all the attention he was receiving.
Then Athena opened the book and read : Introduction.
Story starts next chapter. I think it is most likely Percy Jackson wrote Percy Jackson and Heroes of the Olympus because he wrote Percy Jackson and the Olympians.
