From the New York Times bestselling author of The Good Sister and The Family Next Door with new novel Darling Girls out soon.

"Hepworth turns up the tension in her latest Australian-set domestic suspense novel. A masterful depiction... makes this a winner for fans of Liane Moriarty and Megan Abbott" Booklist (starred review)

Everyone in this family is hiding something.

You may get to choose your partner, but you don't get to choose your mother-in-law.

From the moment Lucy met Diana, she was kept at arm's length. Even after marrying Oliver, Lucy knew they'd never be close.

But who could fault Diana? A pillar of the community, an advocate for social justice, the matriarch of a loving family.

That was ten years ago. Now, Diana has been found dead. There is a suicide note, but the autopsy reveals foul play. And everyone in this family is hiding something . . .

A thrilling page-turner about that trickiest of relationships.
