I have a twin brother. Everyone calls him Jimmy, which is sort of the English version of Dimitri, his actual Greek name. Our mum’s Greek, you see. I’m Cally, short for Calista, which means, I don’t want to sound big-headed or anything, ‘most beautiful’. I’m not sure about Dimitri, but if Dimitri means most-annoying-brother-in-the-whole-wide-world, then that’s him.

Join Cally and Jimmy in four hilarious stories, perfect for newly confident readers. They get into scrapes together, bake some poisonous cakes, almost ruin their school assembly and finally have a twintastic birthday party.
