Local Northern California author Lewis Perdue wrote the first edition of "Slatewiper" as an eBook in 1996. At that time, no one had thought of mapping the human genome, and yet that's part of what this book is about. He wrote an updated version of the book in 2002, and that's what I read.Protagonist Lara Blackwood has done pioneering work which has allowed her to develop gene therapies for such ethnically evolved ailments as cystic fibrosis, Tay-Sachs and sickle-cell anemia. She is ousted from her position in the company she developed by a cabal that has figured out how to use the same research to create biological weapons aimed at specific ethnic groups.As Lara untangles all of the particulars to determine who is behind the work, her life is (of course) endangered. The action ranges from Washington, DC, to Holland and Japan, and there is rarely a dull moment.The ideas for this book come from Perdue's historical research into World War II and also his background in molecular biology. I was entertained by this novel and reminded very much of Michael Crichton's medical technothrillers. Crichton fans are likely to enjoy Perdue's work.
