JUST AT A MOMENT when the study of gay history and literature is flourishing, social critics have declared the death of the GLBT subculture due to the rapid assimilation of gay people, especially those born after Stonewall. The last major gay civil rights battle, marriage, should be won within a generation. Does this mean that the hidden gay worlds some of us inhabited well into the 1970’s are now nothing more than artifacts to be studied? Or do stories from those years resonate with a human significance beyond time and place and circumstance? These questions are raised by Brett Josef Grubisic’s ambitious first novel, The Age of Cities.
