Walking up in a dark,wet and cold place with a bullet so close to her heart. She doesn't remember who she is, her name, her family or anything else. The only person who is there to help her is her father, George. Is he her real dad and can she trust him?
Who is she? And what is her story behind all the nightmares?

Most importantly, why does the man in her dreams keep telling to be careful because they are coming to her to kill and finish all healers forever. What does that mean ? Who are they?
