PositiveOpen Letters Review...this book is anything but derivative ... Williams fleshes out that story not only with clear explanations of the science involved but also with a broad, colorful gallery of personalities ... this author has a dramatist’s ear for crafting sharp, memorable personality profiles ... the result of 500 pages of this kind of evocative, personality-driven drama is a far more involving and engrossingly readable account of DNA’s story than anything bookstores have seen since Siddhartha Mukherjee’s 2016 book The Gene. No apologies necessary for that.
