Percy Jackson and the son of Order

Betrayed,banished,pain that's all I felt.
My name is Percy Jackson and the fates are cruel to me, the love of my life is cheated on me, my friends left me, my father disowned me, and it all started with my half brother Jack Willow.
The only one who stayed with me is Nico he has stayed with me we have both been betrayed, we are like brothers, he joined me in Tarturus.
We want revenge
Than a my real father shows up and offers us a deal
It is too good to turn down.
