"This is one of the best books on genetic engineering for the general reader. It covers the entire field from crops to pharmaceuticals to human gene therapy; it is admirably clear, and the author explains exactly what procedures are being carried out at the genetic level. Most books to not. If you are asking yourself, "What exactly are they doing?" this is a good place to begin."-- Michael Crichton
