The Kidnapped by Nicole Pyland

When she sees a picture of a little girl who looks just like her younger self in a book about lost children, Heidi realizes she was born Hollis Richardson and that she’d been stolen from her mother. After thirty years apart, they’re finally reunited, but being kidnapped by her father has made Hollis lonely, forever changed, and wondering how she can ever forgive him for the time she’s lost with her mom.
Raleigh Leonard’s daughter was kidnapped when she was three years old. Now, over a year later, Raleigh is beginning to lose hope that she’ll ever see her again, but a detective, Dylan Easton, has agreed to help her find new leads and, hopefully, her daughter. To help her cope, Raleigh attends regular support group meetings for people like her, and that’s where she meets Hollis.

The timing couldn’t be worse for the two women, but they discover there’s something between them that’s worth pursuing, even when nothing else in their lives seems to be going right.
