Book excerpt: Karl and Rosa's family watch in horror as Hitler's troops parade down the streets of their home city -- Vienna. It has become very dangerous to be a Jew in Austria, and after their uncle is sent to Dachau, Karl and Rosa's parents decide to send the children out of the country on a Kindertransport, one of the many ships carrying refugee children away from Nazi danger. Isolated and homesick, Karl ends up in Millisle, a run-down farm in Ards in Northern Ireland, which has become a Jewish refugee centre, while Rosa is fostered by a local family. Hard work on the farm keeps Karl occupied, although he still waits desperately for any news from home. Then he makes friends with locals Peewee and Wee Billy, and also with the girls from neutral Dublin who come to help on the farm, especially Judy. But Northern Ireland is in the war too, with rationing and air-raid warnings, and, in April 1941 the bombs of the Belfast Blitz bring the reality of war right to their doorstep. And for Karl and Rosa and the other refugees there is the constant fear that they may never see their parents again. Based on a true story -- there was a refugee farm at Millisle and among its occupants was a young boy called Karl.
