Strap on your seat belt, because this is not your gray-haired father’s harmless hobby. At times it reads like an Agatha Christie mystery with twists and red herrings.

Are we nature, nurture or both? ... Copeland walks the reader through how genetic testing works, with just enough detail to leave you confident in the results (seriously, this is how schools ought to teach biology). But even if 20 pages later you’ve forgotten the difference between autosomal and mitochondrial testing, you will be able to follow along without any trouble ... Like any good reporter, Copeland casts her net wide when looking for sources to interview ... At times reading this book, you get the sense that we are on the edge of some brave new world. It’s exciting, and a little frightening too. Even if you think (like everyone does) that your family tree holds no uncomfortable surprises, Copeland will make you ponder just how much stock we put into our genetic heritage.
