Every book has a word that arrives before the rest of the story does. For me, it was sorrowroot — a name I had before I knew what the flower looked like, what it meant, or who would be holding it.
I knew two things going in: it needed to be small and unremarkable enough that a girl who'd grown up surrounded by rarer, showier blooms would still call it her favorite. And it needed a use — "for wounds of the heart" — specific enough to mean something the first time it's said, and devastating the second.
The color came last. Pale blue, the kind that shows up in a clear sky or a robin's egg, with petals creased like the pages of a book left open too long. Once I had that image, the rest of the symbol built itself: a flower that looks delicate and is anything but, handed between two people who have every reason not to trust each other.
That's usually how it goes for me. The name shows up first. The meaning catches up once I've spent enough time sitting with it.
