I made this cake for my friend's birthday - she is obsessed with the books! I bought the icing book covers from The Cupcake Company. The rest of the toppers are handmade from fondent. The big cake is vanilla, with the spine and front fondent and the "pages" are made of buttercream. I havent yet got round to reading the books(!) so some of the detail isnt 100% - apologies to hardcore fans
