Under the Dark Moon by Susanne Bellamy

Meg Dorset escapes Darwin after the city is bombed by the Japanese. Travelling south in a truck filled with injured soldiers, she meets the charmer, Seamus Flanagan. In the confines of the army camp at Adelaide River, it doesn’t take long for them to fall in love and become engaged. When Seamus is shipped out to join the war in the north, Meg immerses herself in her work and is transferred to the RAAF hospital in Townsville.
On arrival, Meg is dismayed to find she is pregnant, but holds the news to herself to avoid the risk of discharge. Working as head nurse to Dr Geoffrey Ransom, Meg pushes away her growing feelings for this kind and dedicated doctor. She is engaged and carrying her fiancé’s child, so she immerses herself into her work.

As her pregnancy develops Meg is torn. How can she continue with the career she is passionate about, and keep her pregnancy a secret?
