I owe a debt of heartfelt gratitude and affection to a lot of people. To Jessica Regel and Laura Arnold-my agent and my editor, two of the most awesome women I have ever met: They conspired brilliantly to get me to write this book in the first place and then went far above the call of duty to make sure they took care of me while I did! Thank you to Jean Naggar and the staff of JVNLA for welcoming me into the fold, and to the wonderful crew at HarperCollins: Editorial Director Barbara Lalicki for her keen insight and support; Maggie Herold, my terrific copyeditor, for making me look much smarter than I am; and Sasha Illingworth, my stellar designer, for making the whole thing look so damn good! Thanks to editor Lynne Missen and everyone at HarperCollins Canada for the warm welcome. Thank you, Mark and Danielle, for your friendship, your New York hospitality, and all the long walks through the Park-especially the ones at night! Thank you, Adrienne, for all the support. Thank you, Cec-monster, for keeping me going for all these many years. Huge love and gratitude to my family-especially my mom-for somehow understanding that I would wind up here, even if it was in spite of myself. And most of all…to John-for so many reasons, not the least of which is, without you, I never would have even made it past “what if?”
