The Case of Louisa Layton

It suddenly struck her that she had no idea where she was. All she could see was a bed, and a wheelchair. A room made of metal. She was stood by the door. Whose room was this? Fear struck through her like lightning.
"Hello?" She called. "Please, help me.. I don't know where I am!"
To her surprise, a voice answered.
"Oh, my God! She's up, she can speak! She's moving!"
"Then we have to leave, and we have to leave now."

The world has gone to pieces. A disease has spread across the world. It starts with your lungs, and then your stomach, and then your brain. Very few know what caused it. Those with the knowledge are searching for a cure whilst hoping the monsters they call Beauties don't find them.
Amongst those found in the rubble in the cities was a child with a curious mark on her forehead in the shape of the crescent moon. She didn't respond like the other people the soldiers had found. In fact, she barely responded at all.
And her name was Louisa Layton.
