When Mary receives a blank diary as a present, she thinks nothing of it. Until she opens the diary, and sees it’s not blank after all.

Ethan gently squeezes my hand as he slides the golden ring onto my finger. But I know we aren’t worthy of happiness. As I look down at my wedding ring, in a blistering flash, I suddenly remember another piece of that pitch-black, rainy night… but I try to focus on Ethan’s gorgeous blue eyes. I know exactly what he’s thinking. We can never tell. All our family, friends and loved ones smile as they watch Ethan and I promise to be together until death us do part. But only we know what that really means…Because we have already killed someone.

I stare at the messages between my husband Rob and another woman, their plans to run away together bringing tears to my eyes as I stand, trembling, in our luxurious apartment. I thought I had the perfect marriage. As our three beautiful children sleep soundly in the next room, I think about our family holidays, our romantic date nights, and the day Rob proposed to me. In the last few months, I haven’t complained about his late-night meetings or got jealous about his weekends away. I trusted my husband. But now I’m questioning everything.

I was so nervous about someone new joining our house share. After everything that happened with my parents, my friends are like my family. Our imperfect, but well-loved house is the only place where I can be myself. But when Poppy knocks on our door, blonde hair, wide eyes, and a friendly smile, we all agree she’s a perfect fit. I just wish I could shake the feeling that I’ve seen her before…

Last night, we celebrated our anniversary. Over candlelight, we talked about the children, our work, and I was so happy, and felt so loved. But the next morning, when I check my phone, there is a message. From a friend. And a string of photos appear of my husband, Will, with another woman: walking along the street holding hands. Going into fancy hotels. Standing at a window, his arms around her, her head on his shoulder…

Every Monday, I meet my writing group in a warm, lively bar to drink a glass of wine or two and share our work. It’s the highlight of my week. I don’t go out much, otherwise. For the last ten years, every time I’ve relaxed, the messages have started again. The black hearts. They’re a warning to remember, as if I could ever forget. Whoever sent them wants to hurt me. They’ve lost me jobs and boyfriends. Is it any wonder I like to hide in fiction?

Tom, my husband, is always watching, controlling my every move. He chooses my clothes, my hairstyle, even instructing what and how much I’m allowed to eat – just ten measly mouthfuls. I’ve become isolated from those I love, forbidden to work and stuck at home to fulfil his every whim. My identity along with my life is long gone. I am slowly suffocating but I know Tom will never, ever let me leave alive. A chance encounter with Savannah changes everything. Tom couldn’t tear his eyes away from her. Could she be my saviour?

My hand trembles as I stare at the anonymous text. On this sunny Saturday morning, our twin ten-year-old boys were playing in the park just down our tree-lined street. But only one of them has come home… and it’s all my husband’s fault. I race to Leo’s study and demand answers. As his face turns white, I know: one of his affairs has turned deadly. I always smell the unfamiliar perfume on his shirt. I try to pretend we are a happy family, for the sake of the children… but now, my child is in terrible danger.

The invitation to her school reunion couldn’t have come at a better time for Chloe Flynn. Divorced, broke and bored at work, she’s living a life her teenage self would hate. Turning the clock back fifteen years might be just what she needs to wipe the slate clean and start again. And then there’s the chance she’ll bump into Nathan Blake, the one she still regrets letting get away…

It was supposed to be the happiest time of their lives. But for newlywed Stella, the dream honeymoon has turned into a nightmare overnight. Her perfect husband, Austin, has vanished without a trace. Alone in Venice, Stella frantically searches for him. But as fear turns into confusion, she finds herself questioning everything she knows about the man she married. Has Austin really abandoned her, or has someone from his past finally caught up with him—the business partner he threatened to sue? The obsessive ex-girlfriend who refuses to let go?

My husband and I are fighting for our lives in hospital after a terrible car accident. But despite my pain, all I can think about is what our families will find behind our front door. The scarf that has been all over the news, belonging to a dead young woman with honey-coloured hair. I have to speak to the police before my husband can. I’m drifting in and out of consciousness, but when I hear my wife talking to the police, accusing me of the murder of an innocent woman, a cold fear grips me. I know I’ve got a temper.

It’s so kind of our neighbours to throw this party welcoming us to our new home. My husband and I finally moved to the right place. A happy, safe street where nobody knows about my mistakes. But I soon learn their smiling faces hide even deadlier secrets… As I take in the little plates of sandwiches arranged over checked tablecloths, the lavish cocktails, and children playing, I finally feel happy in my new home with Owen. I love hearing the gossip from the local families; the whispers about which wives I should avoid, and which husbands sneak out at night.

I tell myself that Max couldn’t kill anyone. He’s a family man now, different to who he was before. Even so, I should go to the police right away. But I can’t. Because if I do, I’m scared they’ll start to suspect me. How much do I really know about the girl in room 12? And if the truth comes out, how far will I go to protect my precious family?

New Year’s Eve, 2023. When Hannah and her friends rent a luxury yacht in an Italian marina, they party in style under the stars until they pass out. The next morning, they are horrified to find they have been cut adrift into the open ocean, with no sight of land and no fuel in the engine. And that’s when the first person goes missing.

Katelyn smiles around at her husband and friends, gathered to celebrate her 36th birthday in their beautiful home decorated with fairy lights. But the next day Katelyn wakes up shaken and terrified in a hospital bed. She doesn’t remember the sweet taste of birthday cake icing, or how angry her best friend was at midnight, or the terrible things her husband said. She doesn’t remember the party at all. When she asks her husband what happened the night of the party he says "nothing". But her blood runs cold at the way his voice lilts slightly. The way it always does when he is lying.
