A forbidden attraction. A risky affair. Frazer and Cora are about to cross the line—and nothing will ever be the same.

Frazer, head midwife at a hospital in Perth, Australia, is trying to make her corner of the world a little better by starting up a programme for at-risk parents. Not everyone is excited about her ideas. Surrounded by red tape, she finally has to team up with Cora, a social worker who is married to Frazer's boss.

Cora is starting to think her marriage is beyond saving, even if she wants to. Feeling smothered by a domineering spouse, she grabs hold of the programme and the distraction Frazer offers with both hands. Soon the two women get a little too close and find themselves in a situation they never dreamed themselves capable of: an affair. As the two fall deeper, both are torn between their taboo romance and their morals.

But walking away from each other may not be as simple as they thought.
