Now, you may have heard all about my famous brother Percy Jackson. But trust me, you know nothing about me. Hey, I never asked to have a brother. Like, NO way. But thanks to a few gossiping naiads, I'm stuck with a mega famous bro that thinks I've spent the last 16 years of my life with my Dad, all happy families and stuff. Well, he's wrong. They're ALL wrong. And I'm gonna prove it. This is the one where a mysterious disease is making demigods stay in a permanent sleep, relying on me and my darling brother to go into the deepest depths of the ocean to find a cure. Fun, I know. Can Aria save the demigods before they are all taken over by the infectious enchanted sleep?
