This book is the result of work done by many individuals. I would like to offer my sincere gratitude to all of them, whether we worked together directly or otherwise. Mary Beth Ray, Ellie Bru, Tonya Simpson, Keith Cline, Vanessa Evans, Mark Shirar, Trina Wurst, and Lisa Stumpf, please accept my most sincere gratitude for the time and effort you put into this project. I wish I could attend the next Pearson Education social gathering and thank you all in person! Ted Kim, thank you for your technical review and feedback; I hope to meet you someday and thank you in person, too.
