Two women. Two explosive secrets. And both are worth killing for.
Mellie anxiously twists her wedding ring around her finger as she stares at the attic door. It's the one place her mother-in-law could have hidden the secret that will undo her. Because all this time, Mellie has been lying to her dream husband about who she really is.
As she searches with shaking hands, she discovers something she never expected. Her mother-in-law has her own dark secret too. It's been here in the attic the whole time. And it has the power to destroy everything.
As her mother-in-law climbs up the stairs, Mellie's heart pounds as she realises her world is about to come crashing down. Both women have secrets worth killing for. But only one of them will make it out of this house alive.
