Joanne Harris was born in Barnsley in 1964, of a French mother and an English father. She studied Modern and Mediaeval Languages at St Catharine’s College, Cambridge and was a teacher for fifteen years, during which time she published three novels; The Evil Seed (1989), Sleep, Pale Sister (1993) and Chocolat (1999), which was made into an Oscar-nominated film starring Juliette Binoche and Johnny Depp. Since then, she has written five more novels; Blackberry Wine, Five Quarters of the Orange, Coastliners, Holy Fools, and, most recently, Gentlemen and Players, plus; Jigs & Reels, a collection of short stories and, with cookery writer Fran Warde, two cookbooks; The French Kitchen and The French Market. Her books are now published in over 40 countries and have won a number of British and international awards. In 2004, Joanne was one of the judges of the Whitbread prize (categories; first novel and overall winner); and in 2005 she was a judge of the Orange prize. Her hobbies are listed in Who’s Who as: “mooching, lounging, strutting, strumming, priest-baiting and quiet subversion of the system”, although she also enjoys obfuscation, sleaze, rebellion, witchcraft, armed robbery, tea and biscuits. She is not above bribery and would not necessarily refuse an offer involving exotic travel, champagne or yellow diamonds from Graff. She plays bass guitar in a band first formed when she was 16, is currently studying Old Norse and lives with her husband Kevin and her 12-year-old daughter Anouchka, about 15 miles from the place she was born.
