I want to thank Domini Stottsberry for her help with the tremendous amount of research necessary to make this book possible. Brian Feehan and Morey Sparks deserve much gratitude for talking rescues and action and answering endless questions! As always, Cheryl, you are incredible! Thanks to Dr. Chris Tong for his patience in trying to teach me about everything from physics to biology, and to Tyler Grinberg and Cecilia Feehan for their help in working with impossible theories. And of course, I would never get anywhere without Manda!
