Title: The Bottle Factory Outing
Passage: The Bottle Factory Outing is a 1974 novel by English writer Beryl Bainbridge.  It was shortlisted for the Booker Prize that year, won the Guardian Fiction Prize and is regarded as one of her best.  It is also listed as one of the 100 greatest novels of all time by Robert McCrum of "The Observer".  The book was inspired by Beryl Bainbridge's own experiences working as a cellar girl in a bottling factory after her divorce in 1959.
Title: John Banville
Passage: William John Banville (born 8 December 1945), who writes as John Banville and sometimes as Benjamin Black, is an Irish novelist, adapter of dramas, and screenwriter.  Recognised for his precise, cold, forensic prose style, Nabokovian inventiveness, and for the dark humour of his generally arch narrators, Banville is considered to be "one of the most imaginative literary novelists writing in the English language today."  He has been described as "the heir to Proust, via Nabokov."
