I’m grateful to many people who helped me during the writing of this novel: Rena Rossner, for her invaluable advice and encouragement over the last four years. She truly is a superagent; Annette Pollert-Morgan, for her vision. A great editor is like a mother to her characters. Her suggestions help their story grow because each comment is given with love. I am so lucky to have worked with Annette on two novels; Cassie Gutman and Katelyn Hunter, for their incredible attention to detail; the entire Sourcebooks team for believing in my books; my mother, for being my most enthusiastic beta-reader and my father for his wonderful critique about the ending (thank you for making it so much better!); my sisters, to whom this novel is dedicated, for their high-pitched and clamorous support; my husband, Eric, for answering multiple questions about medical procedure, and for more than twenty years of patient listening; and to my three daughters, Aviva, Miriam, and Talia, whose teenage voices fill my novels and my life.
