Everyone thinks my life is bliss. The love of my life, Cary, and I live in our dream home and we have a beautiful little girl, Harper. I may not have given birth to her, but I’m her mommy now. But there’s one thing we never talk about… Cary’s wife before me, Presley, was perfect in every way. But she went missing a long time ago. Cary was distraught when he told me how she was abducted from her car, leaving behind a pool of blood. No one saw a thing. The neighbors are always gossiping about Presley. I try to ignore them, but one day I hear something that makes my stomach flip.

Alex and I haven’t been dating for very long when I go to his place for the first time. Feeling self-conscious as I notice a thread coming loose on my dress, he pours me a glass of wine and I take in the pristine room and expensive furnishings. Everything here is perfect, too perfect. Where are the personal touches, the souvenirs from his life? Where are the photos of his friends and family? ‘You can trust me,’ Alex says as he hands me the wine, and my heart beats wildly in my chest. I really want this to work, especially after the disaster of my last relationship.

I gaze across the candlelit table into the eyes of the man I love. It’s our anniversary dinner, a celebration of our marriage, of how far we’ve come. But within hours our romantic date has ended in murder… When I wake in a hospital bed, blinking under the blinding white lights, I hear someone saying there has been an accident. My heart misses a beat when I recognize my husband’s voice. He says I was driving the car. He says I’ve killed someone.

Standing in my bathroom, the luxurious marble tiles cool under my feet, I stare at the test in my trembling hand. The second line is unmistakable: I’m pregnant. This is all my husband Theo and I have ever wanted, but I didn’t think it was possible. I should be excited, but all I can think about is telling my stepdaughter. Because Ellie’s always hated me, ever since she realised it was no longer just her and Theo. Now she’s seventeen, beautiful and smart–smart enough to see through me. And if Ellie decided to uncover my secrets, it wouldn’t be just my marriage at stake… it would be my life.

The moment I first gazed into Alex's soulful gray eyes, I knew I'd met the man I wanted to spend my life with. And I was right. When my beloved sister vanished, Alex put up posters and wiped away my tears after bad dream—she put me back together. But when police pull a crumpled photo from my dead sister's pocket, and I see my husband's familiar face smiling back at me, my perfect world shatters.

On a brisk fall night in a New York apartment, 35-year-old Billie West hears terrified screams. It's her lifelong best friend Cassie Barnwell, one floor above, and she's just realized her infant daughter has gone missing. Billie is shaken as she looks down into her own arms to see the baby, remembering—with a jolt of fear—that she is responsible for the kidnapping that has instantly shattered Cassie’s world.

It only took a moment for everything to go wrong. In the blink of an eye, the birthday party became a nightmare when we heard the screams… How did this happen? And who is to blame? I’m so happy as I walk to pick up my son from the party. It’s his first since we moved here, and I know he’s found it hard settling in. Just as I’ve found it hard to make friends among the mothers at the school gates. But as I turn the corner, my heart stops. Instead of the picture-perfect birthday party I left earlier, there’s an ambulance.

She knows everything about you… but can you trust her? I walk in to my interview with Ava Green and carefully hand over my application. It’s all made up, of course, but Ava doesn’t have to know that. There is so much worry in her blue eyes. Her phone pings with constant messages and a small stain marks her crisp shirt. Breakfast with her two little girls before heading out to this high-flying job every morning can’t be easy. Ava needs me, I think. More than anything.

We were the perfect family once. Shep, my handsome husband. My darling little boy… and our tiny baby girl. The night she died I lost everything. I know without a shadow of a doubt that I would never, ever have hurt her. I was trying to save her. But nobody believed me. So, I can only watch through the rain-streaked window as Shep’s new girlfriend plays mother to my son. Hugs him, holds him. Does he even remember me? Now I am finally out of the hospital, I will make sure everyone knows what really happened. I will get my son back. The doctors might say my nightmares are dangerous…

Ever since my daughter Isa was born, I’ve been struggling. I can’t remember anything, and my brain is in a fog. So when my husband Ned suggests we hire a night nanny, I leap at the chance. As soon as she walks into our home, I feel a wave of relief. I smile at her and notice her eyes are the color of amethysts. A memory flashes across my brain, but before I can grasp it, it’s gone. But something isn’t right. Ned is acting strangely and every time I ask him why, he tells me I’m being paranoid.
