I am deeply grateful to psychiatrist Dr. Martine Lamy, MD, PhD, and psychologist Dr. Michelle Madore, PhD, for their assistance in reading an earlier draft of this book and making comments. Any errors that remain are, of course, mine and mine alone.
My wife, Hannah; my editors, Cindy Loh and Rebecca McNally; and my faithful Second Reader, Will Hill, all made invaluable suggestions that helped me in the shaping of this story. It was a hard one to marshal, and without all of them it would be a mess. Thank you.
