It’s sort of in the nature of an homage to the local Starbucks. My husband takes me there sometimes when I get stuck on, err, writing, and then we sit there as I drink hot chocolate with peppermint syrup or a chai latte, and I tell him what my problem is and he offers a fix, which  I then proceed to ignore. The shelf where you can take a book and leave a book is at that Starbucks, or at least it used to be; I haven’t been there in a while.

When I’m back in the U.S., I’ve consistently lived in the same neighborhood—Rosslyn, which is in Arlington County, just outside of D.C. It’s where the Foreign Service generally houses us during training. And every time I come back, which is usually at two- or three-year intervals, something else has disappeared. This last time, they ripped down a beautiful little 1950s fire station—the actual Fire Station 10 of the title. It was a shock: It was such a classic building, I was sure they would preserve it, but nothing is sacred around here.

In most fairy tales, protagonists end up with The One because it fits the story: like they’re both royal, or because one has a heart of gold, or sometimes because of a fairy’s meddling. In a story where there’s one royal and one poor but kind-hearted person, of course they get together. This could also be the effect of growing up with Disney’s Golden Age. It’s sort of my same problem with shoujo manga: It’s never a mystery who will end up together.

The seed of this story came to me in a nightmare, actually. I dreamed I was in the suit and something had chewed right through my arm. Usually the inspirations that come with sleep aren’t worth much in the light of day, but I still wrote down every detail I could remember. I hadn’t been getting good sleep since the birth of my second child. Tossing and turning had stirred up some vivid imagery and I put it to use. The rest of the story was developed over several revisions.

I can remember reading, at age eleven or so, Patricia C. Wrede’s Dealing With Dragons, in which Kazul informs Cimorene: “Queen of the Dragons is a totally different job from King, and it’s not one I’m particularly interested in. Most people aren’t.” And that made a great deal of sense to my eleven-year-old self. Growing up on Tamora Pierce and Mercedes Lackey, I was more interested in swords, bows, and hawks than whatever princesses were said to do before they were married off in horse-trading deals.
