Roger Pielke reveals how sports stars break the rules in their search for a competitive edge. Both entertaining and thought-provoking, THE EDGE not only visits the battlefields in the war against cheating and corruption, but also explores ways to ensure that "the spirit of sport” can survive in today’s high-tech, highly professional world. Drawing on controversies straight out of the headlines, Pielke looks at doping, match fixing, fake amateurism, and other ways of breaking the rules. But are those rules--and the values they reflect--hopelessly outdated? Wonderfully readable and scrupulously researched, THE EDGE blends science and journalism to produce an unforgettable account of sport in crisis.
