Fifty Shades of Grey is a 2011 erotic romance novel by British author E. L. James. It is the first installment in the Fifty Shades trilogy that traces the deepening relationship between a college graduate, Anastasia Steele, and a young business magnate, Christian Grey. It is notable for its explicitly erotic scenes featuring elements of sexual practices involving bondage/discipline, dominance/submission, and sadism/masochism (BDSM).
The second and third volumes, Fifty Shades Darker and Fifty Shades Freed, were published in 2012. Fifty Shades of Grey has topped best-seller lists around the world, including the United Kingdom and the United States. The series has sold over 90 million copies worldwide and been translated into 52 languages, and set the record as the fastest-selling paperback of all time. Critical reception of the book has been mixed, with the quality of its prose being generally seen as poor. Universal Pictures and Focus Features plans a film adaptation scheduled for a February 13, 2015 release.
