This holiday is the first time my husband Jeff and I have been on our own in years, and I want it to be a fresh start. We can walk along the beach, eat ice cream in the bright Spanish sun, and fall in love again.

I thought my sister was happy. I thought what we all thought: that Annie and Dom led perfect lives in a lovely cottage in a quiet village by the sea, with flowers at the front gate and an apple tree in the garden. Everyone knew them: generous, loving Dom, creative, joyful Annie. But I never saw Annie as she sat waiting for Dom well into the night. I didn’t see her smiling through her tears. I didn’t know what the perfect couple was hiding.

Ava only left her daughter in the pushchair for five minutes. The buckle was fastened, and she was sure it was safe. But when she came downstairs, the door was open and Abi was gone - she walked down the road, past the Lovegoods' house, and was never seen again. A year later, the Lovegoods throw a housewarming party, showing off the results of their renovation. Ava doesn’t want to go. She can’t bear to look down that end of the road, to see the place where Abi vanished, and she doesn’t want to spend time with people who don’t share her grief.

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....

Hannah has done everything to make sure her life is safe and secure. A long way from her unstable childhood growing up in foster care, she’s content with her sweet, little, messy apartment and her satisfying job as a social worker. She quietly worries that, aged 36, she might never fall in love. But otherwise her life is where she wants it to be. Until, encouraged by her best friend to join a dating app, she meets Alex. He’s irresistibly handsome. He loves the same music as her. The same food as well.
