Blue Paige by Danny Vinik
In this sordid interracial polysexual tale of murder and desire, two half-brother: Joe, a Black republican cartographer in New Mexico and Barry, a white gay junkie nightclub doorman in Los Angeles, find themselves intimately and inextricably involved with Paige, a porn superstar. Joe, whose map-making business is thriving, finds Barry - whose life as a junkie has hit bottom - a job driving a van across the vast desolation of the West. Using sophisticated computer mapping techniques, Barry stumbles across a place not on any map - a ranch cum satellite internet video sex operation - being run by a shady character known only as The Man from the West. When Joe is mysteriously murdered, Barry is forced to delve into the secrets of a man he never knew, his own brother, and compelled to find out just how things got to this point, this particular pornographic moment in the history of our Americas.
