On opposite sides of the pond, Sonia Butt, an adventurous young British woman, and Guy d'Artois, a French-Canadian soldier and thunderstorm of a man, are preparing to go to war. From different worlds, they make their way to fight in Winston Churchill's secret army against the German forces and, unlike most involved in the world's deadliest conflict to date, to fight from behind enemy lines. Their lives first intersect during clandestine training to become agents with the Special Operations Executive. Sonia and Guy learn how to parachute into enemy territory, how to kill, blow up rail lines, support the French resistance, and eventually... how to love each other. But not long after their hasty marriage, their love is tested by separation, by a titanic invasion - and by indiscretion. Written in vivid, heart stopping prose, we follow their stories of uncommon courage - as Sonia plunges into Nazi-occupied France and slinks into black market restaurants to throw off German forces who knew she'd arrived, while at the same time participating in sabotage operations against them by night; and as Guy, in another corner of France, trains hundreds into a resistance army, fashioning himself a military leader, weapons instructor, and peacemaker all at once. Reconstructed from hours of unpublished interviews and hundreds of archival and personal documents, Ayed tells a story of sacrifice and youthful folly; a story about the ravaging costs of war paid for disproportionately by the young. But more than anything, The War We Won Apart is a story about love: two secret agents who were supposed to land in enemy territory together, but were fated to fight the war apart.
