This is the journal of Joe Necchi, a junkie living on a barge that plies the rivers and bays of New York. Joe's world is the half-world of drugs and addicts—the world of furtive fixes in sordid Harlem apartments, of police pursuits down deserted subway stations. Junk for Necchi, however, is a tool, freely chosen and fully justified; he is Cain, the malcontent, the profligate, the rebel who lives by no one's rules but his own.
