I would like to thank Jeff Riley (the acquisitions editor) and Margot Malley (my agent), who made this book possible. Thank you Susan Brown Zahn (development editor) for your valuable guidance and encouragement. It was a terrific experience working with Que's team; their contributions added much to the book. I admit having fun talking about and even sparring over the details. Every book purchase is a nod to Que's preeminent team.
