So the reason I love this post (besides the obvious of it being PJO related) is the agreement that Percy Jackson would/should die.
I don’t want him to, and yes, if he is killed I’m rioting and throwing the book, but I would also understand it. Not only would I want to see custody battles with him in the underworld/afterlife like @luriuan mentioned, but also because Rick Riordan practically confirmed it himself.
In the intro of the first book, he says, “Am I a troubled kid? Yeah. You could say that. I could start at any point in my short miserable life to prove it…”
I have a theory that the entirety of the PJO, HOO, etc is all told from Percy’s POV after he died. That there is going to come one quest that he won’t be able to complete. And. It’s. Gonna. Be. HEARTBREAKING.
I feel like the series will lead to that point:
We all know that Percy’s fatal flaw is his excessive personal loyalty, and that he will give everything to protect his friends and family. Like Athena said in the Titan’s Curse: “Your fatal flaw is personal loyalty, Percy. You do not know when it is time to cut your losses. To save a friend, you would sacrifice the world. In a hero of the prophecy, that is very, very dangerous.”
In the end, I think that Percy will learn once more to let go. I think he will embrace death after giving everything to save the people he loves (similar to Chalice of the Gods).
But the conclusion to the last book in the series could go something like this.
Look, I didn’t want to be a halfblood.
Being a halfblood is dangerous. It’s scary. Most of the time, it gets you killed in painful, nasty ways.
But I wouldn’t change a thing. I could start at any point in my short, miserable life to prove it, but it’s not that bad. Being a halfblood gives you family. Gives you love. Gives you power, and purpose. It give you sacrifice. It’s challenging, and I’ve wanted to give up so many times, but being a halfblood gave me something to live for. And something to die for, which is much more powerful.
If you’re a normal kid, reading this because you think it’s fiction, great. Read on. I envy you for being able to believe that none of this ever happened. But if you recognize yourself in these pages – if you feel something stirring inside – use everything you learn. Take notes if you have to (I can’t believe I just said that.) You might be one of us. And once you know that, it’s only a matter of time before they sense it too, and they’ll come for you. And when they do, follow them. There’s always a home for you at Camp Half-Blood.
Don’t say I didn’t warn you.
My name is Percy Jackson. This is my story.
