To my American publisher Tom Doherty, for extraordinary faith and generosity that I hope will all be justified in the end. To Jim Frenkel, the editor who wisely turned down the first outline of this book when I offered it to Dell back in 1978, telling me - correctly - that I wasn't ready yet to write such an ambitious novel. To my British publisher, Anthony Cheetham, who has believed in my work from the start of my career, and has patiently waited for this book far longer than either of us bargained for. To my editor Beth Meacham, for being a friend, adviser, and protector through the preparation of this and many other books. To the many readers who have written to me urging me to return to Ender's story; their encouragement helped a great deal as I struggled through the most difficult writing project of my career so far. To Fred Chappell's graduate writing workshop at the University of North Carolina at Greensboro, for looking over and responding to the first draft of the Qing-jao storyline. To Stan Schmidt at Analog, for being willing to publish such an extraordinarily long portion of the novel as the story "Gloriously Bright." To my assistants, Laraine Moon, Erin Absher, and Willard and Peggy Card, who, serving well in such completely different ways, gave me the freedom and help that I needed in order to write at all. To friends like Jeff Alton and Philip Absher, for reading early drafts to help me ensure that this hodge-podge of characters and storylines actually did make sense. And to my children, Geoffrey, Emily, and Charlie, for being patient with me through the crabbiness and neglect that always seem to accompany my bursts of writing, and for letting me borrow from their lives and experiences as I create the characters I love the most.

Above all, I give my thanks to my wife, Kristine, who has suffered through every arduous step in the creation of this book, raising questions, catching errors and contradictions, and - most important - responding so favorably to those aspects of the story that worked well that I found in her the confidence to go on. I have no idea who I would be, as a writer or as a person, without her; I intend never to have occasion to find out.
