She's waiting to become a mother-but first she has to find her own.

Weeks away from the birth of her first child, Georgie should be enjoying the peace of her new life in the country, but boredom has settled in and nerves are running high. A viral news story about the rescue of a missing child warms her heart until she sees the photo: the woman who found the child is her own mother, Nancy, who disappeared twenty years ago.

How could Nancy have abandoned her own children? Georgie needs to know before becoming a mother herself, even if it means calling on her estranged brother Dan for support. As the siblings set off on a road trip towards the Scottish island where Nancy was last seen, they don't yet know that her side of the story has just as much heartache as their own.

Caught between her new life and old secrets, Georgie must make peace with the past. Can she and Dan unite to uncover the truth? And can piecing together Nancy's story fix their broken family-or are some wounds too deep to heal?
