Dawn's Requiem. Nightwalker, #3

The year is 1914, and the world is holding its breath. In a hidden Manhattan convent, Alice Bladewell has finally found peace, shepherding a flock of vampires toward redemption through faith and discipline.  But the shadows of her past have long memories. When the Order of the Morning Dawn surfaces within the U. S. War Department, they present Alice with a brutal ultimatum: provide twelve vampire "assets" for the European front, or watch her mentor, Bishop Harkins, be destroyed by scandal. Forced from her sanctuary into the blood-soaked trenches of Ypres, Alice must lead her sisters and brothers into a conflict that threatens to consume what remains of their souls.
