There used to be an empty chair at the back of the class, but now a new boy called Ahmet is sitting in it. He’s nine years old (just like me), but he’s very strange. He never talks and never smiles and doesn’t like sweets – not even lemon sherbets, which are my favourite! After learning that he has fled his own war-torn country, Ahmet’s classmates have “The Greatest Idea in the World” – a magnificent plan to reunite Ahmet with his family. An unexpected and often hilarious adventure follows, all topped off with a terrific twist.
