A perfectly paced psychological thriller that sucks you in, sticks with you and shakes your very core. Deborah has written a fantastic debut novel. Highly recommended. The story is told from Heidi’s perspective and starts off really well. We get to witness her growing fixation with the boy she believes is Jason’s son, which is maybe exacerbated by the fact that, as far as they’re aware, Jason’s son is still alive. She didn’t have the chance to help her daughter and sees this as an opportunity for a happy ending, reuniting Jason and Barney. Heidi and Jason don’t have the happiest of memories in common, and Heidi’s obsession with the boy doesn’t help their faltering relationship. This is where it went a little off kilter for me. I found Heidi’s actions questionable at best.
