Geraldine McCaughrean – Year of election 2010
Geraldine McCaughrean, author of 150 books, is best known as a children's writer, although she has also written several historical novels for adults. She has won a number of awards, including the Carnegie Medal, several Smarties Book Prizes and the Whitbread Children's Book Award – she is the only writer ever to have won this award three times. She claims that while “shyness and timidity are not generally the most useful job qualifications, it meant that, as a child, I spent plenty of time enriching my social life with imagined places and characters”. Now, she “fantasizes for a living.”
