Reviewer Penny Watkins: Penny is a Registered Nurse and specializes in Clinical Informatics. She is also a wife, mom, grandma, activist, coffee lover, cat owner and book addict. Faith and family are her priorities and reading is her second favorite activity. (Sleeping is #1--in my spare time.) She agrees with Margaret Mead: "Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has."
