Secrets and Shadows: Two Friends in a World at WarPaperback, 24 November 2012

When her home is destroyed in the Luftwaffe bombing of the North Strand, Dublin in 1941, Grace Ryan is forced to move in with relatives in a different part of the city. There she meets Barry Malone, an English boy sent to neutral Ireland to escape the terrible air raids on his native city of Liverpool.

Wary of each other at first, Grace and Barry become friends when she acts to stop him being bullied in his new school. Barry later saves Grace from losing her part-time job in a shop and, with school about to end, a summer of fun stretches before them in the sports club run by his teacher, Mr Pawlek.

However, Barry begins to suspect Mr Pawlek of spying for the Nazis and he enrols Grace in his attempts to find proof. But what starts as an exciting challenge becomes increasingly risky, and their friendship is put to the test when their very lives hang in the balance.
