I've read all of Robin Cook's books. In this novel he re-introduces recent medical school graduate, Pia Gradzini. Pia postponed participating in a medical residency in order to do research in a Boulder, Colorado company exploring the wonders of nano technology and its possible uses in curing medical diseases, among other uses. While the book was interesting I found the ending rather un-interesting - in fact it had sort of a "Deus ex Machina" feeling about it. Nevertheless, I think it's worth reading if you like Cook and enjoy medical thrillers.
