Unicorn Variations is a collection of stories and essays by American author Roger Zelazny, published in 1983.  The title story, "Unicorn Variation", was written as a result of Zelazny having been asked to contribute to two different upcoming anthologies — one collecting stories set in bars, and one collecting stories about unicorns.  When Zelazny mentioned these requests to his close friend George R. R. Martin, Martin told Zelazny of a third upcoming anthology — one which would collect stories about chess — and jokingly suggested that Zelazny write a story about playing chess against a unicorn in a bar, so that he could sell the story three times.  Zelazny did just that and then went on to win a Hugo Award for the story. "The Doors of His Face, the Lamps of His Mouth" is a science fiction novelette by Roger Zelazny.

Wilfred Edward Salter Owen, MC (18 March 1893 – 4 November 1918) was an English poet and soldier, one of the leading poets of the First World War.  His war poetry on the horrors of trenches and gas warfare was heavily influenced by his mentor Siegfried Sassoon, and stood in stark contrast both to the public perception of war at the time and to the confidently patriotic verse written by earlier war poets such as Rupert Brooke.  Among his best-known works – most of which were published posthumously – are "Dulce et Decorum est", "Insensibility", "Anthem for Doomed Youth", "Futility", "Exposure" and "Strange Meeting".
