1918: German troops flood back from the Russian front for an all-out assault in France. The under-strength British reel back; the spectre of defeat haunts the land. In the front line, Bertie struggles to bring out his battered battalion; at home Jessie, carrying his child, faces her family's censure. Thomas follows the Romanovs to Ekaterinburg as Russia descends into bloody civil war. Emma drives an ambulance in the FANY, and Jack is shot down. In the last, terrifying year of the war, the Morlands are more than ever in the thick of it, winning through by courage, steadfastness and love.
