The novel's main character, David Selig, is an undistinguished man living in New York City. David was born with a telepathic gift allowing him to read minds. Rather than use his ability for any greater good, however, Selig squanders his power, using it only for his own convenience. At the beginning of the novel, David earns a living by reading the minds of college students so that he can better plagiarize reports and essays on their behalf.

As the novel progresses, Selig’s power grows more and more weak, working sporadically and sometimes not at all, and Selig struggles to maintain his grip on reality as he begins to lose an ability on which he has long since grown dependent.
