Following his father's suicide, Jonathan Holiff discovers hundreds of letters and audio diaries, including secretly recorded phone calls with Johnny Cash during his crazed pill-fueled 1960s, triumphs at Folsom and San Quentin, marriage to June Carter, and his conversion in the early 1970s to born-again Christian. These artifacts tell the story about how Holiff Sr. and Cash collaborated to create a superstar, while each struggled with personal demons. A fascinating behind-the-scenes view of the complex relationship between the notorious singer and his long-suffering manager--it is also a catharsis for its maker and engrossing journalism to boot.
