Rejection - Pernico
Shortly after the Second War, Percy's not-so-little secret comes out: he's not straight. Chased by the Romans who've been won over and led by Octavian, he flees to the Isle of Shadows, where Nico currently resides. Together, they discover another plot to bring down the demigod camps, and eventually strike down the gods, yada yada yada. Will the forces of evil just take a freaking break!?
[[edit: set after Blood of Olympus, except Annabeth and Percy stay at camp, and Nico doesn't. Also, this was written before BoO, so things are a little au.]]
