When Aisha comes across a pale, skinny boy called Richard in the school washrooms, of all places, she is as surprised to meet a 1940s boy as he is to see a black girl wearing a headscarf. Aisha is transported back sixty years to the time of the Blitz, when her school was a sanctuary for East Enders fleeing the bombing. But Richard becomes more than just a friendly ghost; he helps Aisha confront her difficulties at home with her mother, where she is torn between two cultures, and at school where a tough schoolmate is determined to give her a hard time. Finally, Aisha decides to find out the history of her area during the Blitz, and what she discovers makes her realise that she must warn Richard about what is going to happen – but how…?
