4.5 rounded to 5 - This novella opened my eyes to some Nazi history that I was unaware of, especially history that occurred in the United States. The value I see in this book is that it is eye opening. It is very short - a quick read....which accounts for the characters not being overly developed. We are told only what we need to know. I would recommend this book. Thank you to BookSirens and the author for the opportunity.
