Samurai Girl is a series of six novels by author Carrie Asai.
 It tells the story of Heaven Kogo, who as a baby was the lone survivor of a plane crash and was adopted by the wealthy Kogo family.
 At age nineteen, she is arranged to marry Teddy Yukemura, but her wedding is crashed by a ninja that kills her brother.
 She escapes to find out her lavish life and family isn't what she thought it was and must train under her brother's friend, Hiro, the ways of the samurai to protect herself and loved ones.
The flight had 26 on board.
 All but two passengers were killed on impact; one died on the way to the hospital, and the other was the lone survivor.
 Of the passengers from throughout the Eastern United States many were on business or vacation.
 There were two International passengers on board: Arthur Levin was born in Lithuania, and Robert Rene Noel Emile was French.
Susanna Cole (née Hutchinson; 1633 – c. 1713) was the lone survivor of an American Indian attack in which many of her siblings were killed, as well as her famed mother Anne Hutchinson.
 She was taken captive following the attack and held for several years before her release.
The Suicide Motor Club is a 2016 horror novel by American author Christopher Buehlman, who also provided the narration for the audiobook edition.
 It was first published in the United States on June 7, 2016 through Berkley Books and is about a nomadic band of vampires and the lone survivor of their blood lust.
 The book ties into Buehlman's prior novel "The Lesser Dead" via the character Clayton, who is repeatedly referenced by "The Lesser Dead"'s main characters.
The Dry Salvages is a futuristic science fiction story of novella length by Caitlín R. Kiernan, published in 2004 as a stand-alone hardback volume by Subterranean Press.
 The story consists of two parallel narratives, one set in the novella's present-day (early 24th-Century Paris) and the other in the novel's past (the 23rd Century).
 Told as a first-person narrative, the story is being written down with three antique ballpoint pens by Audrey Cather, an exopaleontologist and the lone survivor of an ill-fated mission to an extrasolar planet, Cecrops, a gas giant orbiting the low-mass red dwarf star Gliese 876.
 The "Montelius" mission included two other human astronauts, Peter Connor (also a paleontologist) and Joakim Hamilton (a biologist), and one parahuman astronaut, Umachandra Murdin (a computer scientist), along with a number of androids.
 Its object was to investigate evidence of an extraterrestrial civilization which had long ago mined Piros, a moon of Cecrops.
 A blend of dystopian sf, Lovecraftian horror, and cyberpunk, along with elements of space opera, the novella paints a grim view of the future and of interstellar travel and alien contact.
 Earth has been ravaged by war, pollution, and violent climatic changes, and the menacing intelligence the crew of the "Montelius" (and its predecessor, the "Gilgamesh") discover on Piros leads to a government cover-up.
 The author uses Audrey Cather's three reconditioned ballpoint pens as a literary device, dividing the story into three sections, "The First Pen," "The Second Pen," and "The Third (and Final) Pen."
 "The Dry Salvages" provides an example of an unreliable narrator, as Audrey Cather continually makes mistakes and contradicts herself regarding events aboard the "Montelius".
The Brunist Day of Wrath is Robert Coover's tenth novel.
 It is a sequel to "The Origin of the Brunists", which told the story of Giovanni Bruno, the lone survivor of a mine disaster that killed 97 of his co-workers, and the first several months of the apocalyptic cult that formed around him, ending in their disastrous scattering.
 "The Brunist Day of Wrath" is set five years later, as the cult returns to West Condon.
Lone Survivor is a 2013 American biographical war thriller film based on the 2007 non-fiction book of the same name by Marcus Luttrell with Patrick Robinson.
 Set during the war in Afghanistan, the film dramatizes the unsuccessful United States Navy SEALs counter-insurgent mission Operation Red Wings, during which a four-man SEAL reconnaissance and surveillance team was tasked to track down and kill Taliban leader Ahmad Shah.
 Written and directed by Peter Berg, it stars Mark Wahlberg, Taylor Kitsch, Emile Hirsch, Ben Foster, and Eric Bana.
Lone Survivor: The Eyewitness Account of Operation Redwing and the Lost Heroes of SEAL Team 10 (2007) is a non-fiction book written by Marcus Luttrell with assistance from novelist and ghostwriter Patrick Robinson and published by Little, Brown and Company.
 The narrative takes place in Afghanistan, where the reader follows Marcus Luttrell and a group of U.S. Navy SEALs.
 It has since seen a 2013 film adaptation of the same name, with Mark Wahlberg starring as Luttrell.
Marcus Luttrell, (born November 7, 1975) is a former United States Navy SEAL who received the Navy Cross and Purple Heart for his actions in June 2005 against Taliban fighters during Operation Red Wings.
 Luttrell was a Hospital Corpsman First Class by the end of his eight-year career in the United States Navy.
The Assault (original title in Dutch: De Aanslag) is a 1982 novel by Dutch author Harry Mulisch.
 Random House published an English translation by Claire Nicolas White in 1985.
 It covers 35 years in the life of the lone survivor of a night in Haarlem during World War II when the Nazi occupation forces, finding a Dutch collaborator murdered, retaliate by killing the family in front of whose home the body was found.
 According to the "New York Times", this novel "made his reputation at home and abroad".
 It was translated into dozens of languages and immediately adapted into a film of the same name that won the 1986 Academy Award for Best Foreign Language Film.
