Waterstones Children’s Laureate Lauren Child, creator of Clarice Bean, Ruby Redfort, Hubert Horatio, Bartle Bobton-Trent and Charlie and Lola, will be in conversation with super-geek mathematician Marcus du Sautoy, consultant and code designer for the Ruby Redfort series. This exciting and unusual combination of author/illustrator and mathematician brings together two of the very best in their fields to discuss the poetry of illustration, creativity, taking time to dream, telling stories with codes and theorems and the excitement of finding the hidden patterns and mathematics in all art.
