Caesar Magazine. He held this position until 1983, when he moved to New York City. Shortly after, he published his first novella, Safe, and became serious about writing the five-book series he had been planning since he was fifteen. He left New York in 1985 to follow a boyfriend to Amsterdam, where he finished Closer, the first book in the George Miles Cycle and Cooper's first novel. To get into the right headspace to write Closer, Cooper regularly took meth. The book later won the very first Ferro-Grumley Award for gay literature. During this time, he supported himself financially by writing for American magazines such as The Advocate, Art in America, and Artforum, the later of which eventually took him on as a regular. Cooper returned to New York in 1987, where he worked on Frisk and several projects including co-curating an exhibit with Richard Hawkins entitled AGAINST NATURE: A Group Show of Work by Homosexual Men, which was open at the LACE in 1988. Cooper returned to Los Angeles in 1990 and continued collaborating with other artists, including composer John Zorn, painter Lari Pittman, sculptors Jason Meadows and Nayland Blake, and others. He also started the Little House on the Bowery curated imprint, which included works from Travis Jeppesen, Richard Hell, James Greer, Trinie Dalton, Derek McCormack, and others, under the independent publisher Akashic Books. In the 1990s, he wrote for Spin and published Period, the last book in the George Miles Cycle, in 2000. His novel The Sluts won the 2007 Prix Sade award in France and a Lammy. Cooper moved to Paris in 2005 and has collaborated with French theater director Gisèle Vienne, composers Peter Rehberg and Stephen O'Malley, and the performer Jonathan Capdevielle on six works for the theater, I Apologize (2004), Un Belle Enfant Blonde (2005), Kindertotenlieder (2007), a stage adaption of his novella Jerk (2008), This Is How You Will Disappear (2010), and Last Spring, a Prequel (2011). The Weaklings was published in limited numbers by Fanzine Press in 2008 and was followed by a full-length collection The Weaklings (XL) in 2013. Since living in France, Cooper has published a number of novels, had a cameo in Christophe Honoré's Homme au Bain, released a book/CD collaboration with Gisèle Vienne and Peter Rehberg, reissued the graphic novel Horror Hospital Unplugged he released with Keith Mayerson in 1997, and curated part of the 2012 Un Nouveau
