This book has benefited from the doting attention of many people, and I’d like to gratefully acknowledge them all. Thank you to Sara Shandler, who so gracefully juggles kindness and smarts, and to Josh Bank and Les Morgenstein, who manage to make stuffy conference rooms seem like such very fun places. Thank you to Lanie Davis, Allison Heiny, Andrea C. Uva, and everybody else at Alloy Entertainment. Thank you to all the wonderful people at HarperCollins, especially Farrin Jacobs for wanting to do this book and for her eleventh-hour brilliance. Thank you to Elise Howard, Susan Katz, Kate Jackson, Cristina Gilbert, Alison Donalty, Barb Fitzsimmons, and Ray Shappell. Thank you also to Claudia Gabel and Ben Schrank, who doted early on. Thank you to Ed Weidenfeld. Thank you to Janet Adelman and Bob Osserman. I am also indebted to all of the insanely knowledgeable librarians at the New-York Historical Society. And big thanks to Ben Turner, who bore stoic witness to more than one hair-pulling episode during this process.
