Sadie and Benedict are highly successful models with the Dreamkidz agency. At 1st, Ice Heaven seems just another product for them to advertise. But as millions of children round the world fall under the spell of it's 365 ice cream flavours, theme parks, TV shows and merchandising, they begin to wonder. What is it about Ice Heaven that makes all these children so happy, passive and well behaved. How Sadie and Benedict track down Ice Heaven's secret ingredient, Factor Lamda, and expose Algernon and Cynthia Goodchild, the wicked tycoons behind it, makes a wild, fast moving, funny and very contemporary story with a flavour of Roald Dahl.
