The Leonard girls / Deborah Challinor.

In 1969, at the height of the Vietnam war, nurse Rowie Leonard is serving a 12-month tour of duty. She supports the war and is committed to caring for wounded New Zealand and Australian troops. After a few months, however, she realises that nothing at all about the conflict is as clear-cut as she'd assumed. Her younger sister Jo, is the opposite, a student at Auckland University, a folk singer and a fervent anti-war protestor. But when Jo falls for professional soldier Sam Apanui, home on leave to visit his ill father, she finds herself torn between her feelings and her convictions. As the three of them grapple with love, loss, and the stresses and sorrows of war, each will be forced to confront and question everything they believed.
