Plot: Some thoroughly dumb people create and then fight nanobots.
That's not a completely accurate depiction of the plot except the part about how all the characters that people this story are annoying as hell. They do and say a lot of completely nonsensical stuff as a sole and unsubtle attempt to create SUSPENSE and TENSION!! All it produced in me was rage. This rage I'm afraid obscured any redeeming qualities this book may have had.
To be fair I wasn't a big fan of the reader in the audio version which may have colored my feelings about the characters.
