One of the reasons HarperCollins has been my most frequent publisher for thirty-three years is that I admired three children’s books published by Harper & Row within a year of each other (the year I was turning nine). Where the Wild Things Are by Maurice Sendak, The Diamond in the Window by Jane Langton, and Harriet the Spy by Louise Fitzhugh were among the seminal books of my childhood—of my life—turning me to fantasy and to truth-telling, at one and the same time if I could manage it. I read to make sense of the fantastic world we’ve inherited; I write fantasy to pay back the favor.
