When it comes to saving yourself, who will you betray?

Louise has a shadowy past that she wants to break free from and when she develops an unlikely friendship with Isabelle, her neighbour, she finally finds the family she’s always yearned for.

But Louise knows more about Isabelle than her new friend realises, more specifically about her imprisoned husband – and the circumstances behind his arrest.

Louise is faced with a choice: to continue lying to her only friend or tell the truth and ruin any chance she has of starting over…
