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.

Sometimes a story grabs hold of you and won't let go.

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.

The material world is simply an expression of the mind; that's what so many fail to see. We're so dependent on what is before us that we discount our intuition. Yet if one dismisses instinct, how can one understand or believe in a world that exists beyond one's sight?

I am one of those authors who believes (perhaps foolishly) that she is in complete control of the story.

I love women being the heroes of the piece. There is just something so dramatic and important about this story [The Nightingale ].

[ The Nightingale ]ended up being a huge undertaking - a daunting amount of research on a subject that many people know intimately, a country I had not yet been to when I first started planning the book, an entire war.
