Burning wings

Austin is a boy who has spent his deceased years in Hell. Always disobeying the King of Hell's rules. Well. That was his old days. 2000 years later Austin wants to prove himself to the King of Hell that he is worthy to be a trusted demon. The King of Hell (Satan) thinks and thinks of a way to make Austin prove himself and he finally finds an idea. Austin is tasked to fall in love with the most powerful girl on Earth. Bailey. Bailey doesn't know of her powers and the uses it beholds; she's simply been a hometown girl from Brooklyn and has been for 17 years. Austin takes the task to his black heart. Believing he won't let Satan down. How wrong he was. Soon after meeting Bailey he finds himself trapped in love for her and his feelings for her grow everyday. Unable to escape. His heart begins to change from his black as coal heart to a pure, love-filled heart. Satan's orders were exceptionally clear. Fall in love with the girl and gain her trust, take her back to Satan to feed on her soul and power but don't at any cost follow his heart. Austin does exactly that. All while this happens Satan watches his every move. Austin unaware that Satan has plans all the way from A to Z. Will Austin tell Bailey of her powers? Will she hate him or still trust him? Will she lose control of these powers? Austin is in a trap of his own. Lose her love and take her to Satan or stay with Bailey and fight for good. Will Satan win or lose? Will good fight evil? With danger in every corner will Austin lose control of himself, lose the girl he's fallen for or win this fight? Only time will tell.
