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.

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’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.    

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....

Staring at the stunning diamond solitaire on her finger, Kaitlin is finally getting the chance to introduce her best friend, Zoe, to her perfect fiancé. She hasn’t known Greg long, but he looks after her, and he loves playing dad to her young daughter. How could she say no when he’s already planned their elopement? As guests arrive, why is Greg acting so shifty? And is that a flicker of recognition on Zoe’s face? And why does she look terrified every time her phone rings?

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. But all I could see was a kind, loving man, struggling with grief, who needed my help. Yet as storm clouds gather above our small wedding ceremony, my hopes and dreams fall apart. None of my husband’s family turns up to support us. Instead of a honeymoon, we have a quiet night in. My wedding bouquet is placed on his first wife’s grave. And then my new stepson tells me he’s sure his mother is still alive.

Tucking her little boy Ollie into bed one night, Sarah notices his beloved teddy bear, which she bought him when he was born, is missing and in its place is a new toy given to him by her ex-husband’s new girlfriend, Laura. When she asks Ollie about it, he begins to shift uncomfortably before whispering, "Laura told me a big secret, and she said I can never tell you." Soon, Ollie is asking to spend more time with his dad and Laura, and shrinking away from Sarah. Then, when she calls to him in the garden one day, Ollie doesn’t answer back. 

I only try on one of Nina’s pristine white dresses once. Just to see what it’s like. But she soon finds out...and by the time I realize my attic bedroom door only locks from the outside, it’s far too late. But I reassure myself: The Winchesters don’t know who I really am. They don’t know what I’m capable of....

Everyone in the village admires Anna because she’s a wonderful mother. Juggling family life with a small sewing business, she’s the one they turn to for a warm hug after a hard day. Her kind, polite daughters are a credit to her - even Bay, her stepdaughter, whom Anna loves as much as her own two girls. But normal family life changes overnight when Anna’s middle daughter’s beauty catches the eye of a stranger in a café. As jealousy erupts between the siblings, Anna’s perfect blended family begins to unravel around her. 

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. 

Everyone’s invited. Someone will never leave. In a grand townhouse rented specially for the evening, Hannah beams at her guests under the sparkling chandelier. Her sisters, her mother and aunt, her best friends...although she’ll miss them all so much when she moves away, tonight is about celebrating the happy times and raising a toast to the future. But the next morning, one of the guests is found cold and lifeless in their pristine white bed. Hannah is desperate to call the police. After all, it must have been an accident.

Our new home was supposed to be a chance to leave our past behind. But was moving here the worst mistake of our lives? All our friends and family were gathered, glasses raised to toast our fresh start. It should have been a night for happiness and celebration. Zac and I had worked so hard for this: our first home together, just minutes from the sea. But the dream quickly turned into a nightmare.

From the outside, my marriage to Zach was perfect: a dream home, a perfect baby girl, and passionate, all-consuming love. But as I cradle my gorgeous baby, I have to accept that the husband who used to be my everything has changed. At first, it was little things: expecting me to keep to a strict schedule, picking out my clothes for me. Now, he controls every aspect of my life: from how much money I have, to when I leave the house, and who I can see. I know deep down, only one of us will make it out of this marriage alive. 

Your best friend. Your worst nightmare.... From the moment they met as children, Sasha knew that beautiful, wealthy, and confident Caitlin would always be her absolute best friend. Sasha would do anything to make Caitlin happy. Even keep her darkest secrets. The years have passed, but their friendship remains. And when Caitlin announces she’s getting married, there is only one choice for the role of bridesmaid. Sasha will make sure Caitlin’s wedding is as beautiful and perfect as she is. Won’t she? 

When Sophie’s life falls apart, she accepts an invitation from a childhood friend, Caroline, to visit her family’s beautiful beach house, miles from the nearest town. The silence is broken only by the rhythmic crash of the waves against the jagged black rocks below. But when Sophie arrives, she finds her friend much changed. Caroline - who used to be so warm and confident - is secretive and on-edge, spending long, unexplained hours away from her family. And then there’s Caroline’s little daughter Lucy - who stopped speaking soon after they moved in.
