Having worked with and met several of the scientists portrayed in this book, I have to say that it is the best recount of scientific endeavor I have ever read. It is a sober and cogent account of what any doctor worth the paper their degree is printed on knows--viruses and bugs mutate, and there is always a lag time between what we fall prey to and what we can cure. Her accounts of African plagues and domestic epidemics are both history and warning, and we should put aside labels like "liberal" and "anti-male" (the one irrelevant and the other ridiculous) to focus on the frightening prospect of a new black death, or a mutated HIV virus that spreads by airborne pathogen. It is absolutely possible, and no one should pass up the chance to read this book and inform themselves of the risks they and their children face.
