Game of Shadows: Barry Bonds, BALCO, and the Steroids Scandal that Rocked Professional Sports b7 Mark Fainaru-Wada and Lance Williams (2006)

 This was another excellent goodwill purchase.  It tells the story of how the track stars, baseball players and other athletes broke a bunch of records in the 1990's and 2000's with steroids and then how they got caught.  It's an entertaining story and there's a lesson in it.
