From Goodreads:

In Martin and John, Dale Peck weaves together two sets of stories to create a haunting, heartrending portrait of an artist in our time. The first is told episodically by John, a hustler in New York, who falls in love with Martin, a man dying of AIDS. Interwoven with these stories is a second set, in which characters named Martin and John appear, but living different lives. The resulting novel is a work of stunning originality that is "inspired and brilliant" (The Nation).
