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.

Kieran Hart has just gone through a divorce and is starting over with a new job at a DNA discovery site. After finding out she’s adopted years earlier, she sends in her sample, hoping to find her birth parents, and instead, finds herself in a police station, being accused of a crime she didn’t commit because her DNA was a match to a homicide. Only, it’s not Kieran’s DNA. It’s her identical twin sister’s DNA. The sister she never knew she had. Carina Whitlock is the top ADA in her office and is on her way to becoming the next district attorney when she is handed the case of Marin May, Kieran’s twin sister. It seems like a fairly open-and-shut case until she spends time with Kieran and finds herself not only believing that Marin might not have committed the crime, but also that Kieran might be more than someone she’s supposed to know through a case. All the evidence points to Marin being the killer and maybe much more than just that, but Kieran can’t stop trying to help her sister and becoming friends and maybe more with the ADA assigned to prosecute the case.
