Setting
Nightflyers is set in the distant future. In the distant past, the humans of the Federated Nations of Earth discovered the stardrive. The Federated Nations of Earth eventually morphed into the Federal Empire. For a thousand years, humanity waged war with an alien species called the Hrangan, which caused the collapse of the Federal Empire. Humanity is interested in acquiring the advanced interstellar technology of the volcryn, an enigmatic alien species.

Plot summary
A nine-member team of Academy scholars from the planet Avalon led by the astrophysicist Karoly d'Branin are searching for the volcryn, an enigmatic alien species with an advanced interstellar travel technology. The main protagonist is Melantha Jhirl, a dark-skinned genetically engineered human who is a head taller than the other scholars. Due to limited funds, d'Branin has hired the services of the Nightflyer, a modified trader owned by captain Royd Eris. The enigmatic Royd keeps to his own sphere of the ship, preferring to correspond with the passengers via hologram. Royd secretly spies on the passengers using computer monitors.

Over the next five weeks, the passengers speculate about the secretive nature of their mysterious captain. The team's telepath Thale Lasamer senses there is something dangerous aboard the Nightflyer. The team's psipsych Agatha Marij-Black drugs Thale with the drug psionine-4 to keep him calm. Things start to take a turn for the worse after the xenotech Alys Northwind accidentally cuts her finger with a kitchen knife. As tensions among the passengers escalate due to the ship's cramped and claustrophobic quarters, captain Royd tells the crew that he is the cross-sex clone of his late trader mother and has lived his entire life in zero gravity space.

Not trusting Royd, Agatha gives Thale a drug called esperon and tells him to read Royd's mind. However, a mysterious force causes Thale's head to explode. Agatha goes into shock. Despite growing unrest among the crew, d'Branin still proceeds with the voyage due to his determination to find the volcryn. Later that night, the cyberneticist Lommie Thorne and Alys attempt to hack into the ship's computer systems in an attempt to investigate captain Royd. A mysterious force opens the airlock, killing the two scholars and causing significant damage to the Nightflyer.

Despite their mutual distrust, the scholars agree to help Royd make repairs to the ship's damaged structure. The xenobiologist Rojan Christopher attempts to cut his way into captain Royd's quarters with a portable cutting laser but is killed by an unseen force. The linguists Dannel and Lindran go to investigate but are also killed by the mysterious force, which possesses their bodies. Royd informs d'Branin and Melantha that the ship is haunted by the ghost of his late Mother. While d'Branin and Agatha travel in a gravity sled to seek the volcryn, Melantha and Royd attempt to retake the ship from Royd's Mother. d'Branin discovers that the volcryn are giant space-faring creatures that live in space.

Melantha manages to destroy the possessed corpses of Dannel and Lindran in the ship's mass conversion unit. Royd manages to subdue his Mother by restoring the ship's gravity but is killed in the process. He becomes a ghost and manages to take control of the ship from Mother. Due to the danger of the ghostly entities aboard the ship, Melantha decides to spend her remaining days aboard the Nightflyer, though rebuffing Royd's pleas to repair the ship. Before she dies, she intends to destroy the central crystal and clear the ship's computers before setting a course to the closest inhabited world. Melantha vows not to leave Royd alone with his dead mother.

Publication history
Originally written in 1980, the 23,000-word novella was published by Analog Science Fiction and Fact. In 1981, at the request of his editor at the time, James Frenkel, Martin expanded the story into a 30,000-word piece, which was published by Dell Publishing together with Vernor Vinge's True Names as part of their Binary Star series. In the extended version, Martin supplied additional backstory on the various characters, and named several secondary characters who were not named in the original version.

Nightflyers is set in the same fictional "Thousand Worlds" universe as several of Martin's other works, including Dying of the Light, Sandkings, A Song for Lya, "The Way of Cross and Dragon" and the stories collected in Tuf Voyaging.

In 1981, Nightflyers won the Locus Award for best novella and the Analog Readers Poll for best novella/novelette, and was nominated for the Hugo Award for Best Novella. The novella was also the recipient of the 1983 Seiun Award in Japan for foreign short fiction.

Collection
The collection is the fifth by Martin and was first published in December 1985. It contains the following stories and novellas:
 * Nightflyers
 * "Override"
 * "Weekend in a War Zone"
 * "And Seven Times Never Kill Man"
 * "Nor the Many-Colored Fires of a Star Ring"
 * A Song for Lya

Film
The novel was adapted into a 1987 film by writer/producer Robert Jaffe. The film is about a group of scientists who begin a space voyage to find a mysterious alien creature, and in the process are victimized by the ship's malevolent computer. It was directed by Robert Collector, using the pseudonym "T. C. Blake" as he left before post-production was completed, and stars Catherine Mary Stewart, and Michael Praed. According to Martin, writer/producer Robert Jaffe probably adapted his script from the shorter novella version, since all of the secondary characters had different names than the ones he chose in the expanded version. The film grossed $1,149,470.

Television
In 2017, a pilot for a possible TV series based on Nightflyers was being developed by Syfy. The series was based on the 1987 film, with Jaffe serving as one of the producers. The script for the pilot was written by Jeff Buhler. Martin was not involved in the production or writing for the new series, since his contract with HBO contains an exclusivity clause.

Jodie Turner-Smith was cast as Melantha Jhirl. Martin expressed his enthusiasm on his journal, and pointed out that her casting more accurately represents the novella's character than the film, which cast a white actress. Netflix co-produced the show and holds first-run rights outside of the United States.

The series premiered on Syfy in December 2018 and was filmed in Ireland.

Syfy announced the series was cancelled after a single season in February 2019.
