Next : a novel / James Hynes.

Enhanced descriptions from Syndetics:

One Man, one day, and a novel bursting with drama, comedy, and humanity.
Kevin Quinn is a standard-variety American male: middle-aged, liberal-leaning, self-centered, emotionally damaged, generally determined to avoid both pain and responsibility. As his relationship with his girlfriend approaches a turning point, and his career seems increasingly pointless, he decides to secretly fly to a job interview in Austin, Texas. Aboard the plane, Kevin is simultaneously attracted to the young woman in the seat next to him and panicked by a new wave of terrorism in Europe and the UK. He lands safely with neuroses intact and full of hope that the job, the expansive city, and the girl from the plane might yet be his chance for reinvention. His next eight hours make up this novel, a tour-de-force of mordant humor, brilliant observation, and page-turning storytelling.
