Cross dressing and singing

When Percy Jackson, son of Artemis is included in a prophecy, he is taken into hiding by his sisters. Well, hidden in plain sight as a girl.

With pretending to be a girl, but actually a gay 12 year old boy, and juggling the fact that he just may be able to save camp half blood by just admitting that he's the lost heir of Poseidon, and the awfully cute son of Hermes Luke Castellan, how will Percy prevail on saving the camp and even his birth mother?
