Blood Will Tell by Jean Lorrah

"What is the difference between Good and Evil? Both Good and Evil people have needs. The difference between Good and Evil is not in what is needed. It is in what will be done to sustain Life. Both Good and Evil people face death if their needs are not met -- death of the soul, death of the spirit, death of the body. Will you take what you need to live, no matter the harm to others? Will you negotiate for it? Trade for it? Will you give it to someone in need? Will you save a life at the risk of your own? Will you give the Kiss of Life? Or the Kiss of Death? " (from publisher)
