When war erupted across Europe in 1939, sixteen year old Katherine Montague had known what she wanted to do - what she had to do. Now, five years later and a trained nurse in the British army, she finds herself thrust into the thick of that same war. But as the fight for the Western Front rages on, Katherine discovers something amid the rubble of the death and destruction around her. Something that will plunge her into a completely new war - a war she'd never intended to fight, but has no intention of losing. The war for William Hughes' heart. Love might be enough to win the battle, but will it be enough to win the war? If not, her own heart just might pay the price.
