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

In the end, the best part of the whole book [The Nightingale ] to me was the research, reading about the courageous, ordinary French women who put their lives on the line to save others. It was really inspirational.

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.

The only truth was whatever you could make someone believe.

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.

There were others, women with stories that were told in a quieter voice: women who hid Jewish children in their homes, putting themselves directly in harm's way to save others. Too many of them paid a terrible, unimaginable price for their heroism. And like so many women in wartime, they were largely forgotten after the war's end.There were no parades for them, very few medals, and almost no mention in the history books.

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.
