I have read this book. It is about a boy called David who escapes a concentration camp in Bulgaria ane flees across Europe, first to Salonika in Greece, and then to Italy by ship and later north through Germany, aiming for Denmark. In Italy he meets a rich family, that gives him food, water, etc. After leaving them he goes into Germany, he is captured by a mean german farmer, later escapes from him. Will he reach Denmark and safety?
