Boy overboard - Morris Gleitzman

Jamal loves playing football, which isn't easy if your goalie only has one leg and you keep having to dodge landmines to get your ball back. Jamal's stubborn little sister Bibi is even better at football than Jamal. But girls playing football is against the law in Afganistan. When it is discovered that Jamal's mother has been secretly running a school, the family must leave their home immediately and begin a long and dangerous journey to Australia. The children survive separation from their parents, hunger, and violent smugglers only to find that Australia isn't as welcoming as they had thought but, even though they face an uncertain future, Jamal, Bibi and their parents know that as long as they are together, that is all that matters.
