This was a fun book to read. Megan Smolenyak is a genealogist who has used her genealogy skills to help a number of other people. In this book she describes many of her "history-mystery" cases she has helped solve. Besides genealogy, Megan has worked with the Army to identify the next of kin for remains found from WWI, WWII, Korean, Vietnam wars. She's also found next of kin for FBI cold cases and NCIS cold cases. The stories in each chapter are fascinating as a history lesson as well as showing how genealogy skills help solve these problems. You learn a little about doing genealogy and a little about the history of our country, as well as things you might find out about your family. There's at least one story in this book everyone will be able to relate to. Plus there are the surprises she's uncovered in her own family. She thought she knew all her family secrets until she did some DNA testing of relatives and discovered her grandmother had a secret. It's an easy to read book and you'll enjoy the matter of fact way that Megan relates these stories.
