The Naughtiest Girl in the School is the first book in Enid Blyton's school series. The protagonist, Elizabeth Allen, is a spoiled, unruly, and determinedly naughty girl who is sent to Whyteleafe School, a progressive boarding school. Elizabeth vows to be so disruptive that she will be expelled immediately. The narrative chronicles her many hilarious and disastrous attempts at naughtiness and her slow, reluctant transformation as she is gradually won over by the school's kindness and the power of friendship.
