In a novel that is stunning in its twists, shocks, and gripping psychological suspense, two sisters find themselves on the razor’s edge of sanity.

Untold secrets, a ghastly lie, and suffocating guilt hold them back. Only one astounding act can set them free. And one last revelation will leave readers gasping in surprise.

Robin and Sarah weren’t the closest of twins. They weren’t even that similar. But they loved each other dearly. Until, in the cruellest of domestic twists, they were taken from one another.

Now, in her early 30s, Robin lives alone. Formerly a famous rock star, now agoraphobic and suffering from panic attacks, she spends her days pacing the rooms of her house. The rest of the time she watches - watches the street, the houses, the neighbours. Until one day, she sees something she shouldn’t…

She can’t be around her new family until she has come to terms with something that happened a long time ago. And to do that, she needs to track down her twin sister.

But Sarah isn’t the only person looking for Robin. As their paths intersect, something dangerous is set in motion, leading Robin and Sarah to fight for much more than their relationship…
