I do not often follow my characters off on tangents or change my story on a whim. I have an outline which I follow quite sternly...for a good long while. Then it turns out in some way to be insurmountably wrong and I am forced to re-think every component. Usually at this point I throw hundreds of pages away.

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.

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.

The only truth was whatever you could make someone believe.

I am more than happy to invite my five favorite fictional characters. Let's see. First on my list is Sam Gamgee from The Lord of The Rings. Sam is a beautiful character; in him, we find the profound heroism of an ordinary person. He epitomizes the saying that courage isn't not being afraid, courage is going anyway. I just love that.

Impatient men are generous ones. Or haven't you learned that by now?

It felt like an oversight to me, something that needed to be corrected. They [women who hid Jewish children] deserved to be understood and remembered.
