Memories New and Old

This is my (original?) version of the Percy son of Chaos story's. I will try not to do the same as someone else, but I've been inspired by quite a few writers so there will be similarities (such as the wings Percy is given, betrayal (but logical betryal), being the commander of the Chaos army (for a while), and bringing back hero's from the dead). All rights to most of the Characters go to Rick Riordan, the amazing and incredible Author of the PJO and HOO series (among others). So- lets get to the real summary!
After the Giant war, everything was peaceful- well as peaceful as a demigod's life can get. There were a few monster attacks here and there, but otherwise, life was good. That is- until an unfortunate event happens and the campers start to get wary of Percy. In the meantime, the son of sea has noticed his love drifting farther and farther away. Then the dreams start, but they seem so real. What will our hero do when this chaos (*ha- pun*) starts?
This is after HOO, but there is no Trials of Apollo. Also, Leo has returned in this.
