WHAT MAKES A MOTHER?
Katherine likes to be in control. Everything clean, everything perfect, all of the time. After years of trying - and failing - to conceive, she finally gives birth to Rose, her IVF miracle child. Yet she's never quite been able to believe Rose is her daughter, her pale skin not matching Katherine's own.
Tess never got her happy ending. She took on IVF alongside Katherine and a group of hopeful mothers, but her daughter Hanna was stillborn. After a series of desperate choices, she's divorced, broke and stuck in a job beneath her skillset.
When Rose is nine months old, both women get a call from the fertility clinic. There was a mistake - two women's eggs were switched. One woman has been raising the wrong daughter, while the other has spent a year grieving a child that wasn't hers.
Katherine's life begins to crumble around her, but for Tess it's the glimmer of hope she needs to keep going. It'll take a custody battle like no other to decide who really deserves to be Rose's mother
- a battle that will push both women to the brink
