'My Sister's Child' and it is the story of two sisters Jo and Isla. Fifteen years ago, Isla donated eggs to her older sister Jo who was undergoing fertility problems. Jo managed to get pregnant using Isla's egg and her husband's sperm. They made two embryos one of which is transferred to Jo and the other was frozen in storage.
Fast-forward fifteen years and Isla is experiencing infertility problems of her own, and with no options left to conceive a child, she decides to ask Jo if she can have the remaining embryo.
The story deals with the tension between Jo and Isla and the dilemma faced by Jo, who doesn't want Isla to have the embryo even though genetically it was conceived using Isla's egg. It also focuses on Isla's intense relationship with her fifteen year old niece. It deals with the moral dilemmas surrounding egg donation and the issue of nature versus nurture - who really is the mother?
