<DIV>Those who have called John McGahern a modern Chekhov are struck by his ability to transform commonplace experiences into moments of epiphany. In “Parachutes,” the narrator reels in the aftermath of a breakup with the woman he loves; “Oldfashioned” is the story of Johnny, a country boy oddly drawn to the elderly English couple for whom he represents the son they lost in the War; and in “Eddie Mac” and “The Conversion of William Kirkwood,” a wealthy family and its hired help learn that the relationship of master and servant is the most enduring relationship of all. <p> In <b>High Ground</b>, John McGahern displays all of his acclaimed mastery, and both deepens and extends the world of his generous imagination. </p></div>
