Everyone brave is forgiven
Chris Cleave2016

London, 1939.
The day war is declared, Mary North leaves finishing school unfinished, goes straight to the War Office and signs up. Young, bright and brave, Mary is certain she'd be a marvelous spy. When she is - bewilderingly - made a teacher, she finds herself defying prejudice to protect the children her country would rather forget.
Tom Shaw finds he will do anything for Mary North. But he decidely ignores the war - until he learns his roommate Alistair Heath has unexpectedly enlisted. And when Mary and Alistair meet, it is love, as well as war, that will test them in ways they could not have imagined, entangling three lives in violence and passion, friendship and deception, inexorably shaping their hopes and dreams.
Set in London during the years of 1939-1942, when citizens had slim hope of survival, much less victory, Everyone Brave is Forgiven features little-known history and a perfect wartime love story inspired by the real-life love letters between Chris Cleave's grandparents.
