In 1902, E Nesbit published Five Children and It, which has never been out of print. Jacqueline Wilson, the highly acclaimed author of Tracey Beaker and countless other children’s books, revisited the original and has created Four Children and It. Her story is set in the modern day and follows Rosalind and Robbie, their half-sister Maudie and step-sister Smash. This foursome’s adventures see them discover the mythical sand-fairy in Surrey's Oxshott Woods. In this event, recorded live at the 2012 Edinburgh International Book Festival, the popular children’s author talks to Jenny Avern about her take on this much-loved story.
