"How do 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 But are those rules - and the values they reflect - hopelessly outdated?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"--Publisher.
