The story of a homeless boy who starts by losing everything, and--through his experience as an evacuee in World War II--finds friendship, vocation, and a place to belong. When Vinnie is sent away from the bombs in London, he has no idea what awaits him--all he has left of his old life is his harmonica. On the train, Vinnie meets fierce Kathleen, sweet Joey, and gangly Dobbs. The evacuee children find themselves thrown together in the country town of Netterfold, which seems beautiful and peaceful--until they meet the locals. There is a war raging across Europe, but Vinnie and his friends soon find they have their own war to fight as they face up to terrifying teachers, bad billets, and hostile neighborhood kids who set out to make their lives as "vaccies" miserable. And when things start to go missing, they discover that there are mysteries lurking in Netterfold's shadows, just waiting to be solved. Through music and friendship, can Vinnie make peace and finally find a place where he belongs?
