Problem Child by Victoria Helen Stone

She’s cold, calculating, and can deceive with a smile. Jane Doe is back in the Amazon Charts bestselling series – and this time she’s met her match.

After a brutal childhood, Jane Doe has been permanently wired to look after herself and only herself. Now, looking next to normal, Jane has a lover and a job. But she hasn’t lost her edge. It sharpens when she hears from her estranged family.

Jane’s deeply troubled sixteen-year-old niece, Kayla, has vanished, and no one seems to care. Neither does Jane. Until she sees a picture of Kayla and recognizes herself in the young girl’s eyes. It’s the empty stare of a sociopath.

Jane knows what vengeful and desperate things Kayla is capable of. Only Jane can help her – by being drawn into Kayla’s dark world. And no one’s more aware than Jane just how dangerous that can be.
