- "In contrast to the previous entries in the series, there is little action here and much talk—about what the war has cost the soldiers in terms of their humanity, the changing roles of women, and the elusive search for love and peace of mind. Still, the many fans of the series will be anxious to know how it ends." Booklist, August 2007
- "The depth and passion of Perry's fifth and final volume in her acclaimed WWI series won't disappoint readers who have followed this engrossing and moving tale from its inception with No Graves as Yet. In the last days of the war, the Reavley family—Joseph, an army chaplain; his brother, Matthew, an officer in the Secret Intelligence Service; and their sister, Judith, an ambulance driver—find themselves together in the mud, blood and trenches of Flanders. Throughout the series, the three have been locked in a deadly struggle with someone they call the Peacemaker, who they believe is a high government official who had their parents murdered in his quest to involve England in an odious peace effort with Germany. A breakthrough arrives with a German officer who's willing to go to England and reveal to the authorities the identity and mission of the Peacemaker, though the family must first solve the mystery of a murdered nurse before unmasking the Peacemaker. At the finish, Perry neatly and satisfactorily ties up all the loose ends from the preceding novels." Publishers’ Weekly (starred review),
