My absolute awe at how poorly this book was written kept me with it through the bitter end. Having read all of Robin Cook's other books I expected some kind of plot to evolve as the book continued. Cook has always had an easy flow to his dialogue, but in this book it is stilted and thick with ridiculous stereotypes. While I don't discourage a foray into different genre', perhaps he could at least write with the same level of conviction he has in the past. I can't believe a good editor and/or publisher who supports the author would let this book go to press.
