Historical tends to be my bailiwick.

[ 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.

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 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.

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.

I know that sounds ineffective and daunting, but it [throw hundreds of pages away] is actually my favorite part of the writing process.

The women of the French Resistance astounded me. Isabelle and Vianne [from The Nightingale] are my homage to those brave and forgotten women.
