High-tech whistle-blower, Jack Forman, is in deep kimshi in Crichton's book, Prey. This is nanotechnology at its worst. Here's a brief review; ---

Jack discovers his wife's firm has created self-replicating nanotechnology--a literal swarm of microscopic machines. Originally meant to serve as a military eye in the sky, the swarm has now escaped into the environment and is seemingly intent on killing the scientists trapped in the facility. The reader realizes early, however, that Jack, his wife, and fellow scientists have more to fear from the hidden dangers within the lab than from the predators without.

--- This is interesting science.
