The trenches of the Great War are a shadowed place. Though Platoon Sergeant Matthew Petticrew arrived there with a past long marked by shadow, the realities of battle bring new wounds–carving within him a longing for light, and a resolve to fight for it.
One night, Matthew and his comrades are enraptured by a sound so pure, a voice so ethereal, it offers reprieve–even if only for a moment. Soon, rumors sweep the trenches from others who have heard the lullaby too. “The Angel of Argonne,” they call the voice: a mysterious presence who leaves behind wreaths on unmarked graves.
 
Raised in the wild depths of the Forest of Argonne, Mireilles finds her reclusive world rocked when war crashes into her idyllic home, taking much from her. When Matthew and his two unlikely companions discover Mireilles, they must embark on a journey that will change each of them forever . . . and perhaps, at long last, spark light into the dark.

On the 100th anniversary of the dedication of the Tomb of the Unknown Soldier comes an emotive tale inspired by the courageous soldiers of World War I.
