Prior to the publishing of Rise of the Red Engineers in 2009 many of Andreas's published writings had been graphic novels. The first of these was The Incredible Rocky, an unauthorized biography of the Rockefeller family. Although Andreas wrote the book while still in high school, it went on to sell nearly 100,000 copies. Next came Made with Pure Rocky Mountain Scab Labor, meant to support a strike by Coors Brewing Company workers. His latest graphic novel is Addicted to War: Why the U.S. Can't Kick Militarism, which has been approved by the San Francisco School District as a supplemental book to be used by high school history teachers.
