Amy and Breanna are half-sisters who grew up bound by shared history, but pulled apart by different lives.

Amy has always felt out of place, shaped by an absent father and a longing for a family. Breanna, younger and more settled, juggles a demanding job, two children, and long stretches of solo parenting.

When years of failed IVF leave Amy with one last frozen embryo-and the devastating news that she can't carry a pregnancy herself-she turns to Breanna with an impossible request. But as old jealousies and the pressures of motherhood begin to surface, the sisters' fragile balance is tested.

Soon, they're both forced to confront who they've become in the shadow of expectations that never quite fit.

Set in small-town New Zealand, MY SISTER'S BABY is a tender, emotionally powerful novel by Susan Edmunds.
