The complete inside story of the shocking steroids scandal that turned the sports world upside down. For years, in the shadowy reaches of the world of sports, there were rumors that some of our nation’s greatest athletes were using steroids, human growth hormone, and other drugs to run faster, jump higher, and hit harder. But as track stars blazed their way to Olympic medals and sluggers brought fans back to baseball, sports officials, the media, and fans looked past the rumors and cheered on the athletes to ever-higher levels of performance. Then, in December 2004, San Francisco Chronicle reporters Mark Fainaru-Wada and Lance Williams broke the story of the Bay Area Laboratory Co-Operative, a tiny nutritional supplement company that, according to sworn testimony, was supplying elite athletes with banned drugs. The stories shocked the nation and the exposés led to congressional hearings on baseball's drug problems and a revived effort to purge the US Olympic movement of drug cheats. Now, in Game of Shadows, Fainaru-Wada and Williams tell the complete story of BALCO and the investigation that has shaken the foundations of the sporting world. And at the center of the story is the biggest star of them all, Barry Bonds, the muscle-bound MVP outfielder for the San Francisco Giants whose suspicious late-career renaissance has him threatening Hank Aaron’s all-time home run record. Shocking, revelatory, and riveting, Game of Shadows casts light into the shadows of American sports to reveal the dark truths at the heart of the game today.
