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 know I'm not normal in this, but [ Severus ] Snape is absolutely my favorite character in the Harry Potter books. He is completely mortal - good, bad, strong, weak, motivated by hatred, motivated by love. A gorgeous, compelling, complex character who definitely earns a spot at my table.

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

Honestly, I really didn't want to take on World War II France, but when I came across the story of a nineteen-year-old Belgian woman who created an escape route out of Nazi-Occupied France, I was hooked.

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?

Andrée De Jongh story led me to other stories of women who joined the Resistance in France. I found literally dozens of memoirs written by women who had become spies and couriers and helped to create the escape network. These women were like action-star heroes.

Sight is one of the most easily deceived senses. I could make a coin disappear and your eyes would believe it gone, even if it were merely up my sleeve.
