This book is a good example of historical fiction. I am not a big fan of books set during WWI, but the author does a good job of describing that particular time period. Florence was well developed and the author allowed you to see Boots as a truly compassionate individual. While you could read this as a standalone, it would be very beneficial to have read the first three books in the series.
