Angel of Shadows (Percy Jackson Fanfic) *rewriting*

A long time ago an angel was cursed for his greediness and his anger. He was cursed to be a demon. When God cursed the angel he also made him immortal. The demon then went to the Devil, and made a deal. "Make me the strongest demon, and I will give you my soul." The Devil eager to get the once angel's soul accepted the deal, yet since it was the Devil he added a tiny thing. If this angel had children then they to would carry the burden of being the strongest demon, but what the Devil wasn't expecting was the demon to fall in love with an angel.

The demon and the angel had a child. A girl. She was very beautiful just like her mother.They named her Bianca, which meant fair and white. A few years after they had Bianca they had a son, but the demon and the angel's son was very ill. They feared he wouldn't make it. The angel sacrificed her life to save her son. After the angel died the demon turned cruel to his son. He was never cruel to his daughter though. Eventually that angered the half angel/ half demon, and he refused to talk to anyone.

Now our story begins....
