“It’s definitely not a ‘big overview of DNA testing’ book, but instead a ‘let’s get down and dirty and solve a brick wall problem’ book. And we definitely need a book like this.”

"This book is unique. My first thought was this is just like the choose your own adventure books I used to read as a kid. It’s almost like having Diahan there to hold your hand while you work your way through your matches and find your family!”
"Diahan Southard and her team always publish thoughtful, organized and helpful DNA products. This workbook is no exception. The workbook helps you to organize your DNA information so it is at your fingertips. It guides you through steps to help you plan your DNA research. The book even asks you questions and gives explanations of your next best steps. There is also an icon for the "Your DNA Guide, The Book" that gives you page numbers to look up for more information. There are plenty of charts and diagrams to keep track of your progress and work. I would highly recommend this workbook for anyone who wants a good example of how to start your research with your DNA matches.
