Betrayed But Back (Percy Jackson Chaos Story)

Percy Jackson was betrayed by everyone he knew. It all started when he found out he had a brother named Evan, and everyone's attention turned to him. All of his friends were gone, but Percy was relieved that he still had Annabeth. At least he thought. Wrong! One day he found her making out with Evan on the beach, the day he was about to propose to her. Hurt beyond words, Percy ran away. But what happens when a mysterious force named Chaos takes him in? And what happens when Percy has to come back to Earth to help Camp Half Blood out with his team?
(P.S. I know that everybody makes these now, but I'm really obsessed with them and wanted to try my own!)
