The child you never knew
knows all your secrets . . .

Out of the blue, Susie Jukes is contacted on social media by Anna, the girl she gave up for adoption fifteen years ago.

But when they meet, Anna's home life sounds distinctly strange to Susie and her husband Gabe. And when Anna's adoptive parents seem to overreact to the fact she contacted them at all, Susie becomes convinced that Anna needs her help.

But is Anna's own behaviour simply what you'd expect from someone recovering from a traumatic childhood? Or are there other secrets at play here - secrets Susie has also been hiding for the last fifteen years?
