Broken wings

Jade is a 15 year old girl who is running non-stop for her life. Ever since her mother and father left it's been up to her to take care of her little sister Emily. Her sister is only 6 year sold but is quite aware of what is going on. They were both fine on their own till the government came after them. Only wanted them for experiments. See they weren't just normal humans like you and me, they had wings. Jade and Emily were considered mutants for their amazing ability and the government wouldn't stop at anything till they got what they wanted. Jade's mom and dad were scientists capable of mutating anything they wanted. So when it came time for them to have children they thought why not experiment, hence where their children had wings. Everything was fine till the government found out and all went to hell. Their parents only thought about themselves so they abandoned their two daughters against the world so they wouldn't get caught. Ever since their mother and father were nowhere to be found giving the government free game at Jade and Emily, but not if Jade had anything to say about it...
