1943 is a dangerous time to fall in love...

In wartime Melbourne loose lips sink ships, so when Australian Women's Army sergeant Stella Aldridge overhears soldiers whispering about a revenge killing, she follows her instincts to investigate, despite finding herself drawn to one of the soldiers, the enigmatic Staff Sergeant Eric Lund.

But the world is at war and there is little time for romance. Someone in the Australian Intelligence Bureau is trading secrets and it's up to Stella and her uncompromising superior officer, Lieutenant Nick Ross, to find the traitor.

When Eric's team is scheduled to be deployed in a dangerous mission to the South West Pacific, Stella races to uncover the truth or risk not only Eric's life, but the security of Australia itself. Torn between protecting the ones she loves and her duty to her country, Stella chooses to pursue the truth at all costs.

Even if it means putting herself in the firing line...
