Alice and Tom Froston navigate danger and discover courage beyond their years in this story of adversity and adventure set during the German invasion of France.

Going on holiday to France just before the German invasion in 1940? A recipe for disaster. That's exactly what Alice and Tom Froston do – and soon find themselves in more danger than they could ever have imagined.

Sent back to Paris by their parents, the train they are travelling in is bombed – but that is only the start of their desperate attempts to get home.

Along the way they face capture by the advancing enemy and encounter a cast of unexpected allies: a downed RAF pilot, a nun with unexpected talents and even a French noble, amongst many others.

With German forces closing in on the British at Dunkirk and France on the brink of surrender, will Alice and Tom find a way back to safety?
