The Golden Feather

This story happens years after the heroes of olympus, after peace in earth is restored (I suppose that's how Blood of olympus ends... well hopefully). Anyway Percy and all the other Half-Bloods we knew are adults and left camp Half-Blood.

''Everything was going as planned, we killed some monsters in the woods and praticed some archery before dinner time but then this strange dude appeared at camp Half-Blood. Well that's when everything started going south.''

-Theo

Sinopsis
Theo and Allie are normal Demigods living in camp Half-Blood, well as normal as a Half-Blood can be. One day a strange guy arrives at the camp, the first strange thing was that he was alone. Secondly he should've been death because he seemed to be 16 years old, monsters should've swallowed him already. But the craziest thing about this guy was that he smelled like a Half-Blood (for the Satyrs of course) but... he hadn't any godly parents, not a single God recognized him.
