We would like to thank Dyana Pearson (Hacker Girl) and Joe Sikes for their input and suggestions. Without their assistance, and humor, this book would not be what it is.

This second edition is dedicated to Helen Young Halton, who was the force of nature that kept Wolf on track for their 14 years of marriage. Helen passed away on Star Wars Day (May the Fourth) in 2017, and so never saw the end of the story. Helen left Wolf and two grown children, Savannah Rogers and Candler Rogers. She would be gratified and proud of the lives into which they are living. - Wolf Halton, Memorial Day 2018
