You're not who you say you are. Neither is she. She thinks she knows me. She believes my marriage is falling apart at the seams, that my husband can barely look me in the eyes. She thinks I’m desperate for a baby, that my longing for a family keeps me up at night. As much as I hate to admit it, all of this is true. She thinks I listen to her advice, that I care about her opinion. That couldn’t be further from the truth. Because she has no idea who I am. She has no clue that I know everything. I know her secret. I know that she did the unforgivable. I know how many lives she ruined.

She’s the shoulder you cry on when the father of your children disappears. She’s the person you turn to when he comes back, begging for forgiveness. She’s by your side when you discover his guilty secrets. She helps rock your babies to sleep when they cry. She’s your friend when you have no one else. She’s the woman upstairs, whose feet you hear treading above as you drift off at night, thankful you aren’t alone.    

I couldn’t believe it when I got the call to offer me my dream job. It was right in the heart of the city with a flat provided. I jumped at the chance, and within days I had made new friends and began dating a wonderful man. For the first time in years, I feel safe. But soon strange things begin to happen in my flat: odd noises in the night, the feeling that I’m being watched. When I discover an old dress hidden behind my wardrobe and wear it to work, the atmosphere chills instantly. The dress belonged to a girl my boss would rather forget. The girl before me who vanished.

Claire has everything she’s always wanted. A newborn baby. A doting husband by her side. A picturesque home in the countryside. But behind closed doors, Claire’s life is falling apart. Her husband is barely ever home, she’s struggling to bond with her baby girl, and she swears that she is being watched in the remote, lonely cottage. And when a threatening note is posted through her letterbox, saying she doesn’t deserve her daughter, it’s clear that someone knows about the terrible mistake that Claire made.

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....

The white-washed Italian villa is perfect. I thought it might feel odd, living in a stranger’s house for the summer, but as my husband and children swim in the infinity pool, I start to relax. And then, in the back of a wardrobe, I find something that shatters everything.... Sparkling green eyes, square jaw, lopsided smile. A young man with his arm around a beautiful woman. The picture is old and faded, but I’d recognize him anywhere. The man is my husband.

My best friend warned me that it was too soon to marry Edward, a widower with an adorable but troubled little boy. She said we were moving too fast.

Two weeks at a stunning villa, in the South of France, was supposed to heal the rifts in this fractured family. Flaky croissants and rich, black coffee every morning before long days by the sparkling pool. Balmy candlelit dinners, once the kids have gone to bed. But Nora is shaking, as she gathers her family around the large, oak table on the terrace, at the front of the villa. Her two daughters eye her suspiciously as she tops up her wine and clears her throat to speak. But when she opens her mouth, the secret Nora came here to tell won’t come out....

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven.
