by Robyn-Rose May, CD. CEF Books 2016; SC; NEW BOOK; 164 pg. Very few Canadians, including Historians and Great War Enthusiasts, realize the sacrifices made by Canadian Nursing Sisters during the Great War. I have to say I was one of those. There are reasons for this; there are very few Nursing memoirs (only three I can think of), and books about the Nursing Service are scarce and hard to find. What was needed was a book that encompassed all the lost Sisters, detailing their lives, and outlining their fate. Now 100 years after the Great War Robyn May has given us what we always needed. Sacrifice of Angels is the definitive study of the lost lives of Canada’s Nursing Sisters in the Great War.
