There are many people who work to put a book together, and although as authors we dedicate an enormous amount of time to writing the book, it would never be published without the dedicated, hard work of the whole team at Wiley. They are truly a fantastic group to work with, and without the Wiley team this book would have never been possible.

First, I'd like to thank Kenyon Brown, my senior acquisitions editor, who convinced me I could do this solo and offered me support and guidance through the writing process. Ken was always there to answer questions and point me in the right direction. Without Ken as a mentor, I could never have pulled this one off.

I can never thank my development editor David Clark too many times; David is a true professional who stayed on top of the schedule and professionally reminded me of the next upcoming deadline I was working to meet. Without David's help, putting this book together would have been much more difficult than it was. Thanks again, David!

Kunal Mittal offered excellent input as the technical editor, and it was great to have him on the team offering his expert advice.

A big thank-you to Dassi Zeidel, the production editor on this project. I am still amazed at how she and her team of professionals could take my work and transform it into such a presentable book. Dassi was great to have on the team and to work with on this project. I'm sure there is a whole staff at Wiley lurking in the background and I will never know how much they helped, but to everyone at Wiley, a big thank-you! You made the late nights and long weekends of writing and putting this book together all worthwhile.
