A HUGE THANK-YOU—always—to Emily Meehan, life-changer and visionary. Endless gratitude to Kieran Viola, editor extraordinaire, who helped shape this book with her pitch-perfect ear, amazing storytelling skills, and patience. Working with you has been an absolute gift and an author’s dream. Thanks also to Heather Crowley, Cassie McGinty, Marci Senders, and the whole talented bunch at Hyperion. You rock! Sara Crowe, my super agent, you make everything possible. Thank you. I could not have finished this book without the love and support of Kayla Cagan and Vanessa Napolitano, dear friends and fellow writers; Penny Hill, library buddy and life support; and my beloved friends and family. Most of all I’d like to thank Henry, the sunshine of my life.
