There are only 5, but there is a new spin off series called the Heroes of Olympus which will be a 5 book series.
The Lost Hero. It is not exactly a Percy Jackson series but it includes Percy Jackson characters and settings. The main characters of the Lost Hero are 3 demigods Jason, Piper and Leo.
YES No. But he is writing a series of books which is a squel to the Percy Jackson series. It's call The Heroes of Olympus: The first book is The Lost Hero. It will be publish on October 2010. The second book with be called The Son of Neptune and will be published in Fall 2011. I don't know which date exactly. But it will have Percy in it, but he will be in the Roman Camp and he won't be the only main character.
there will most likely be a 6th. after all the ending had a new prophecy of 7 NEW heroes. not to mention Olympus has to be rebuilt as well. Percy has to get thrown out of school again or it will be a let down to the series. i liked the books so much i immediately waned a new book to come out
no
Yes, there is going to be a 6th and a 7th book.
If you read the heroes of olympus, you see that its quite clear who are the 7 demigods. Of course, our main protagonist is one of the 7, but without memory. I can tell you who i think are all 7. Percy Jackson Hazel Levesque Frank Zhang Leo Valdez Piper McLean Jason Grace (the 7th is unknown right now, but keep a look out for the newest book, Mark of Athena)
I'm assuming you mean the second book in the Heroes of Olympus series, because though the two series link together they are not the same. They have different main characters and overall plots. Anyway, Son of Neptune comes out October 11, 2011.
Depends on which book.I'll do them all:Lightning Thief:In this book Percy is just another 12 year old who hates he life.Jet Black hair, Sea Green eyes.Sea of monsters:In this book Percy is a 7th grader who try's to hide the fact that he's a demigod. Also because of his ADHD and dyslexia he's just another target for bullys (even though he could kill them if he wanted 2!)Titans Curse:In this book Percy is an over stressed 8th grader.Also his attitude is bad almost the entire book(EXCEPT at the beginning BEFORE something bad happens)Battle of the Labyrinith:In this book Percy Act's more like a teenager, just under EXTREME stress.Hope that's enough!Last Olympain:In this book Percy is an Over-stressed kid who wants to die. until he wins the 2nd Titan war and the world feels like heaven!! (the very end is where percabeth starts)
