This is a hardback book.
From the dust jacket: "Michael Storrs's joy comes from physical danger-as a parachutist, a surfer, a hang glider, a free faller, a reckless skier. Oppressed by his life in New York City, he feels choked by his career as an executive in a high-powered office, choked by the airless world of air-conditioned towers.
His own sanity depends on his finding a purer, simpler, more vigorous existence, and he sets out to search for one, even though he loses his wife in the process. He finds the physical excitement he craves-but along with it developments he has not contemplated. For some of the personal relationships in which he becomes entangled prove as threatening as the most dangerous of his sports."
