The title of this book does not give away anything of the true message/theme of the book. I almost appreciate that because I have to suspend any previous notions I may have about a particular subject.
I learned a great deal about at least one superstition that surrounded the spread of disease, in this case consumption or what is known today as tuberculosis. The doctor that Lucas Whitaker was apprenticed too stood on the cusp of change for the medical profession, one that made great discoveries about the tiny creatures invisible to the naked eye that we now know as microbes.
This is a great children's book to teach about history, science and superstition yet not too burdened with details that would bore a child or make a child put down the book.
I definitely recommend this book.
