Going back to the normal world

A couple of months after Gaea was defeated, Percy Jackson went back to Goode high school to get his mind off everything that had happened during the war to stop her. Anyway Percy Jackson is doing great nothing weird has happened since he's been back at school, until the head teacher calls an assembly and when Percy Jackson and a group of his mortal friends arrive in the hall only to be greeted by none other then the gods themselves... unknown to Percy the gods have decided that it's time to tell the world about demigods and what better way to do that then by tell everyone about Percy Jackson.
