The main plot covers a short time period leading up to the presidential election in the United States. The story is fast paced, and the novel is hard to put down once you get involved in the plot. There are lots of people with guns, and some collateral damage. The advantage shifts back and forth between good guys and bad guys, but the good guys have some unexpected allies, and sometimes there is a "falling out among thieves."There is a final wrap-up set a year later.
There are some technical explanations of both psychological loss of senses (in this case sight), and of the heightened senses some people develop. This last point was interesting as I have always been able to sense people behind me, but did not know how to account for that ability.
