Zack is well known as a gay artist, but the pen name is also shared with his prartner Roger M. Kean. After careers in film, journalism, magazine publishing, and historical reference publishing, Kean settled down to pen gay fiction. Writing as Zack, the “Boys of…” series extends to five full-length illustrated novels. The Adventures of American Gil Graham and Brit Mike Smith are set in the early 1980s, all published by Bruno Gmünder in paperback and ebook formats. By the same publisher Zack has written BLOOD AND LUST, THE WARRIOR’S BOY, RAW RECRUITS and DESERT STUDS. Already published in the "Boys of Imperial Rome" series are DEADLY CIRCUS OF DESIRE and THE SATYR OF CAPRI, with THE WRATH OF SETH due in August and TWISTED BLADE IN THE ARENA in the spring of 2017. Under another pseudonym, Bruno Gmünder recently published Zack/Kean’s pulp fiction novels MISSISSIPPI HUSTLER and a story of 1950s Hollywood MULHOLLAND MEAT.
