11/22/63 is a novel by Stephen King about a time traveler who attempts to prevent the assassination of John F. Kennedy which occurred on November 22, 1963 (the date of the novel's title). The novel was announced on the author's official site on March 2, 2011.[1] A short excerpt was released online on June 1, 2011,[2] and another excerpt was published in the October 28, 2011 issue of Entertainment Weekly[3] The novel was published on November 8, 2011,[4] and quickly became a number-one bestseller. It stayed on the list for an additional seventeen weeks. 11/22/63 won the 2011 Los Angeles Times Book Prize for Best Mystery/Thriller and the 2012 International Thriller Writers Award for Best Novel,[5][6] and was nominated for the 2012 British Fantasy Award for Best Novel[7] and the 2012 Locus Award for Best Science Fiction Novel.[8] The novel required deep research to accurately portray the late 1950s and early 1960s.[9] King commented on the amount of research it required, saying "I've never tried to write anything like this before. It was really strange at first, like breaking in a new pair of shoes."[9] The novel's time-travel premise marks it as science fiction, specifically the alternative history subgenre, although the extensive period research undertaken by King, dealing with real-life events and people between 1958 and 1963, gives it a strong feeling of historical fiction. http://en.wikipedia.org/wiki/11/22/63
