What next? (PJO fanfic)

The backstory

Above is a random pic of ummm something sent by a friend. You ask me why that picture and my answer is why not. Now on with the story ...

Hey,sooo.... you want to know about my life? Well in my seemingly short life, now never ending by the way, there are few people who try especially hard to get on my bad side one being Larry Barnesuque (thx _stormhawk111_ for the name) .

Why do I hate him you may ask. Well that is a very good question little one. Well that is because he ruined the perfect life that I had.

He took my fame, which wasn't very important to me, and then he took my friends and family. He reminded them of all the things that I had down that weren't my best moments. He reminded Nico that I got his sister killed. He reminded Clarisse about Selina and the Hephaestus cabin about Beckendorf. He told everyone about how I supposedly abandoned Annabeth before her solo quest. But the worst part was that everyone believed him.

But the main part was Annabeth's betrayal. She was the only one stopping me from running away to Alaska before the end of the summer and her betrayal hit me the hardest.

~~~~~~~~~~~~~~~~~~~~~~~~~~

I was unusually happy that day considering everyone's betrayal and the war still laying heavily on my shoulders but today was the day. Annabeth and I had decided that we would soon move into New Rome and today was the day I was going to take her there myself after proposing to her. You probably think that I was too young to be thinking about that at the age of 19 but I was actually one of the oldest living campers and since demigods tend to have a shorter life, many actually get married by 25 or less if they survive that long. Anyways, I was walking to our evening meeting place at the edge of the beech nearest the amphitheater to tell her that I was back from my solo quest when load cheers broke out from the amphitheater. I realised that they were too big to be for a claiming and ran towards the sound, knowing that something big had happened. When I reached there everyone turned silent, looking at my with mixed expressions of contempt or sympathy making me wonder what exactly had occurred there. Then I reached the middle. There in the centre was Annabeth and Larry. In a tight embrace but worst of all, lip locked passionately.
"I realise that I've been gone for a while, but I didn't think you would move on so quickly."
My words had shattered the lingering silence better than I could have hoped. Annabeth turned to me immediately, but Larry however merely protested quietly and continued making googly eyes at Annabeth.
"It's not what you think." Annabeth had said looking at me with fake anxiety. At this Larry finally looked at my with thinly masked hatred,"Actually it's exactly what you think. Annabeth doesn't love you and has been planning to break up with you ever since you left on your silly little quest."
I looked at him disbelievingly but he just gestured to Annabeth's hand. Then I realised what was off with her fidgeting. She was trying to hide the glittery ring encircling her ring finger. I just stared at her for a moment, comprehending what had happened during the time that I was gone.
Annabeth again tried to defend herself,"I thought you were dead Percy, what did you expect me to do while you were gone? Larry comforted my and he spent more time with me than you ever did."
That's where I came out of my trance. Ignoring everyone else except for Annabeth, I pulled out the ring that I got for her.
"I guess you won't be needing this then." I said sarcastically. I heard many gasps when people started to get a good look at the ring. It was a silver and gold ring with three gems on the top. One was a clear diamond, which had been enchanted to assume the colour of everything around it. So at that moment it was filled with flames and swirls of the reflection of people standing around me. The other two were beautiful grey gems, which were carved lightly into oval shapes. Overall, I think it was the best ring I have ever seen anyone wearing in my life up till then. And in one smooth throw, it landed in the campfire's roaring flames, where it sparked and then exploded into dust emitting a wave of power before dissipating into the night air. And with that I waltzed out of camp with my quest bag, which was still with me. Not looking back even once; preparing myself to start a new life alone.

That time seems insignificant now as it was around 500 years ago. This is the story of everything that happened after.
