Mackenzie Wark invents a new genre for another gender: not a memoir but an auto-ethnography of the opacity of the self. Another genre for another gender. What if you were trans and didn't know it? What if there was some hole in your life and you did not even know it was there? What if you went through life not knowing why you only felt at home in your body in peak moments of drugs and sex? What if you expended your days avoiding an absence, a hole in being? Reverse Cowgirl is not exactly a memoir. The author doesn't, in the end, have any answers as to who they really are, or were, although maybe they figure out what they could become. Traveling from Sydney in the 1980s to New York today, Reverse Cowgirl is a comedy of errors, chronicling the author's failed attempts at being gay and at being straight across the shifting political and media landscapes of the late twentieth century. Finding that the established narratives of being transgender don't seem to apply to them, Wark borrows from the genres of autofiction, fictocriticism, and new narrative to create a writing practice that can discover the form of a life outside of existing accounts of trans experience: an auto-ethnography of the opacity of the self.
