Cuban literature is the literature written in Cuba or outside the island by Cubans in Spanish language.
 It began to find its voice in the early 19th century.
 The major works published in Cuba during that time were of an abolitionist character.
 Notable writers of this genre include Gertrudis Gomez de Avellaneda and Cirilo Villaverde.
 Following the abolition of slavery in 1886, the focus of Cuban literature shifted.
 Dominant themes of independence and freedom were exemplified by José Martí, who led the modernista movement in Latin American literature.
 Writers such as the poet Nicolás Guillén focused on literature as social protest.
 Others, including Dulce María Loynaz, José Lezama Lima and Alejo Carpentier, dealt with more personal or universal issues.
 And a few more, such as Reinaldo Arenas and Guillermo Cabrera Infante, earned international recognition in the postrevolutionary era.
"Soldier Boy" (also known as "X Minus One #71: 56-10-17 Soldier Boy") is a 1953 science fiction short story by American author Michael Shaara, about a soldier who, when sent on a routine patrol to a colonized world, saves the planet from an alien and its robot attack devices.
 Despite an ingrained contempt for the military that arose as part of conditioning to avoid war, the human colonists gradually assist the soldier when strange occurrences suggest they are not alone on the planet and may be, like several other colony planets, under threat of extermination by outside forces.
 It was originally published in the July 1953 issue of "Galaxy Science Fiction".
 It is also the title of a 1982 collection of Shaara's short stories
