I’m hugely indebted to my agent, Sam Copeland, for making all this happen. And I’m especially grateful to my editors—Ben Willis in the United Kingdom and Ryan Doherty in the United States—for making the book so much better. And for all their helpful comments, suggestions, and encouragement, I’d like to thank Hal Jensen, Ivàn Fernàndez Soto, Emily Holt, Victoria Holt, Vanessa Holt, Anna Bingemann, James Haslam, Uma Thurman, Diane Medak, Nedie Antoniades, and Joe Adams.
