"The New York Trilogy" is a collection of three interrelated novels by author Paul Auster. The books—"City of Glass," "Ghosts," and "The Locked Room"—explore themes of identity, language, and the nature of reality through the lens of detective fiction. Each story features a protagonist who becomes entangled in mysterious circumstances in New York City. The trilogy is notable for its postmodern style, blending elements of traditional narrative with metafiction. Auster's work challenges readers to question the boundaries between fiction and reality, as well as the roles of the author and the reader in the storytelling process.
