This instant national bestseller, for readers of The Nightingale and Lilac Girls, is a dazzling novel about a spy and a pilot who fall in love but are wrenched apart during World War II, and must find their way back to each other.

When Billy Coke steps onto the streets of London one December evening in 1940, he has no idea he is stepping to his fate. As Hitler's bombers come close to burning the city down, Billy meets the woman who will change the course of his life: Ilse Magnusson, a musician from Norway, but also something more—a spy in training.

Escaping the Blitz for three days, she and Billy drive, quarrel, conceal, reveal . . . and fall finally, fully, in love.

Now they must part, each to fight the war their own way. Billy, a Canadian Spitfire pilot, to duel with the Luftwaffe over North Africa and the Med. Ilse to return to her conquered country, ingratiate herself with the Nazi elite—which includes her beloved father—and send vital intelligence back to Britain.

They know that the odds of both of them surviving are poor. All they can hope is that the other does survive—and that someday they find each other again.

From decadent pre-war Berlin to the atrocity at Guernica, from dogfights over Sicily to an Oslo ground under the German jackboot, through small victories and bitter losses, this is the story of a man and a woman at war. A tale of causes and compromises, heroism and betrayal. Of choices made, with consequences unforeseen. And finally, how sometimes . . . love can give you a second chance.
