Paul's Daughter

This story is about percy having a step sister but this isn't how most percy+sister fanfics go.
Paul is actually a descendant of a greek god, along with that he had an affair with a greek goddess, he doesn't know he is descended from a greek god and does not know that his daughter is also the daughter of a greek goddess.
Your probably wondering why Paul was never attacked, he himself had a very weak Aura so most monsters walked right past him and the few who found him his mother took care of.
Paul may have been weak, but all th e power he had bottled up was given to his daughter, his daughter he had forgotten about, but she hadn't forgotten about him.

Dedicated to @stressrepublic for giving me the idea. Go read their books they're really good.
