Realising she can no longer ignore the loud ticking of her biological clock, Dr Cate Davis makes a decision that will challenge friendships and alter the course of her sensible, well-planned life. Tom, her good-looking but emotionally elusive best friend, offers his assistance as a sperm donor. Expecting him to make his donation and leave her to the business of parenting, Cate is about to encounter some unforeseen circumstances!Supported by a close-knit and endearingly dysfunctional group of friends and family with secrets threatening to tear them apart, Cate wonders if she knows herself, Tom or anyone as well as she thought. Between the surging hormones and rising emotional stakes, she begins to doubt her own instincts – especially as fresh revelations sweep her from South Africa to Switzerland and back again. Can she balance everything important to her, or will it slip from her grasp?
