Hi I Have A Dear Friend Who Suffered A Stroke,

Hi I have a dear friend who suffered a stroke, I heard of an MD who had trouble dialling 911 and it was a terrible ordeal getting help. She was in coma and said to be hopeless, her mother nursed her back to health and she is practicing again, do you know the title and author of the book she wrote, i don't know her name but she wrote about it i would like to give my friend some hope because her daughter says it it pretty bad she was in a coma after surgery. i hope you can help me
