Knowles wrote a book called Our Gods Wear Spandex: The Secret History of Comic Book Heroes (2007), which won an Eagle Award for "Favourite Comics-Related Book". He co-authored a book published in 2008 about The X-Files TV series called The Complete X-Files: Behind the Series, the Myths, and the Movies. In October 2010, Viva Editions published his latest book, The Secret History of Rock 'n' Roll, which Voice of America says presents rock and roll as having its roots "in the mystery cults of the ancient world", then "follows the evolution of rock 'n' roll from an expression of youthful rebellion to a symbol of American culture."[4]
