" This is a fictionalized account of smallpox in England and in Boston in the early 18th century. While many people are familiar with the story of Jenner and vaccination against smallpox using the cowpox virus, fewer people are aware of the process of variolation, which used small amount of smallpox to give the recipients a milder case which protected them from the disease. This was practiced in Africa, Turkey and the far east and was "rediscovered" and brought into practice by two brave people, Lady Mary Wortley Montagu, a survivor of this terrible disease. and Zabdiel Boylston, a doctor in Boston. Each took much risk to spearhead the use of this practice, and in some ways, suffered for their beliefs. The author has done an enormous amount of research into smallpox and the history of variolation and does a nice job of building a full story about each side rather than just a recitation of the facts.
