This book began in Hawaii, during a serendipitous meeting with my future acquisitions editor at New Harbinger Publications, Tesilya Hanauer. Tesilya’s enthusiasm for the book idea carried me through the long process of development, writing, and editing, and she was always responsive with helpful feedback. She was a tireless champion for the book long before its publication was a sure thing. I am deeply grateful for her faith in me and her unwavering excitement about the idea.
