Every call she ever made to him, every text she ever sent, every photo of him has been wiped from her phone. His social media accounts have vanished.

Our new home was supposed to be a chance to leave our past behind. But was moving here the worst mistake of our lives?

A young woman turns up at a police station. She has been kept prisoner in her own home. Abused and tortured, her every move watched, her every thought controlled. Now she's finally escaped. That's what she says. But when the police arrive at the address she's given them, her story doesn't seem to add up. Her husband is missing, but his phone and wallet are still in the house. She says she's the victim, but what if she's not? What if the stories she's telling aren't her stories at all....

They don’t know what I’m capable of....

She bursts into my life like a storm, and nothing is the same again. One by one, I watch as my friends fall under her spell. Only I see that her smiles don’t reach her cold, furious eyes. And when I’m accused of things I didn’t do, when my home is vandalized, I know she’s behind it. But she only lets her mask slip when no one is looking, so if I say anything, I’ll look crazy. So when the baby shower comes around, I’m sitting on a velvet sofa in a posh hotel room, surrounded by balloons. But that afternoon, I finally learn the unbelievable truth. There is no baby....
