When Aisha meets a pale, skinny boy called Richard in the girls' toilets, she is as surprised to meet a 1940s' boy as he is to see a Somali girl. Aisha finds herself transported back to the time of 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, where she is torn between two cultures.
