I am very much enjoying books telling stories from the perspective of vulnerable. « The secrets we left behind » tells the story of British nurses left behind during the army’s evacuation from France at the beggining of the WWII. Cate, a brave nurse and Jack, her rescued patient, meet two French sisters who shelter them under the nose of Germans. The story takes time to unfold, so you might need to be patient at the beginning. The author tried to show us that even during unbelivable hurdles humans can fall in love. I found though this part a bit overboard, perhaps because all female characters fell in love one after another.
The background scenery serves well its purpose, so that the mind can picture and place the characters in Normandie at the time of the action.
