The BFG (short for "Big Friendly Giant") is a 1982 children's book written by Roald Dahl and illustrated by Quentin Blake. It is an expansion of a short story from Dahl's 1975 book Danny, the Champion of the World. The book is dedicated to Dahl's late daughter, Olivia, who died of measles encephalitis at age seven in 1962. As of 2009, the novel has sold 37 million copies in UK editions alone.
The story is about a young orphaned girl named Sophie, living in a girl's orphanage run by the cantankerous and abusive Mrs. Clonkers. One night, Sophie sees a large, cloaked person blowing something via a trumpet-like object into a bedroom window down the street. She is discovered by the mysterious person, who carries her to his homeland of Giant Country. There, he identifies himself as the Big Friendly Giant ('BFG'), who nightly blows bottled dreams into the bedrooms of children, and explains the other type of giants that eat humans, mostly children. Because the BFG refuses to eat people or steal food from humans, he subsists on a foul-tasting vegetable known as a snozzcumber.
