ACKNOWLEDGMENT

It is due to the extraordinary contributions of Amy Halliday, our professional writer and editor, that you now hold this book in your hands. With patience, good humor, and tact, Amy helped us to transform our widely varied experiences into the written word. Amy showed us time and again through her own example what it means to be a good writer. We thank her for endless hours of review and restructuring, for rescuing us countless times from our own writing gone awry, and for the gifts of her editorial insights that helped us to craft 25 chapters into a book.
