There are a lot of people who made this book possible, and even more who made it better. I owe particular thanks to:
My agent, Sarah Davies, for her invaluable feedback and her unwavering conviction that what I'd written was, in fact, a story.
My editor, Lexa, who understood my book, then showed me how to fix it.
Ben Schrank and the Razorbill team, for making a mysterious process less mystifying.
My Merry Sisters, Tessa Gratton and Maggie Stiefvater--Tess keeps me honest and Maggie keeps me from rusting.
Gia for surprise candy-delivery. Also, driving me around when I was sleep-deprived, thereby keeping the roads much, much safer.
Little Sister Yovanoff for taking excellent pictures and writing down all the parts where she was confused.
My husband David, who believed unfailingly--even on days when I didn't.
And Syl, who has always been willing to read everything I write, and then tell me exactly what she thinks.
