3.5 stars
In this last book of the Aunt Jane’s Nieces series, the girls are upset by news of the Great War (WWI) in Europe. Although the United States is remaining neutral so far, the nieces and their Uncle John decide to join the Red Cross as nurses and ambulance drivers to help the wounded French and Belgian soldiers near Dunkirk. Their friend volunteers his yacht as a hospital ship, and Uncle John provides all the necessary supplies. They obtain their approval from the Red Cross, their nurses’ training, and their official credentials, but they still need a surgical doctor who will volunteer to join them. Uncle John hears of a medical man with a severely disfigured face who might be willing to help, but they will have to convince him that his features are not an obstacle.
