In doing the research, I found myself consumed by a single, overwhelming question, as relevant today as it was seventy years ago: When would I, as a wife and mother, risk my life - and more importantly, my child's life - to save a stranger? That question is at the very heart of The Nightingale. I hope that everyone who reads the novel will ask themselves the question.

I see the emphasis on a lot of ideas and I know that's directed at me. [Megan Chance] come up with an idea, hone it, and write it. I come up with thirty ideas, flesh each one out, research each one, come up with characters, and then decide I don't like it.

The woman who led [downed airmen] was named Andrée De Jongh and her story - one of heroism and peril and astounding courage - became the inspiration for my novel.

Coming up with the idea is the worst part of writing for me.

Thematically, we're both [with Kristin Hannah ] interested in women's experiences and women's stories, and until now, you've mostly dealt with how it feels to be a wife/mother/sister/name your poison in today's world. But this story [The Nightingale ] is told from the perspective of two sisters during the German occupation of France in WWII.

I simply couldn't walk away from [ The Nightingale].

The only truth was whatever you could make someone believe.
