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.

Pushing down the memories of the terrible childhood that ultimately tore them apart, she arrives at her sister’s house. Cecily has left instructions: how to work the oven, what to cook for supper, what to say to her husband. She says she’ll only be gone a week.

Handsome, devoted and kind, he should be the ideal man for her, but Sarah knows their marriage is the biggest mistake she’s ever made…and she wants out.

Handsome doctor Matthew Delaney and his wife Nicole have a perfect life. So when Matthew suddenly vanishes, Nicole is in shock. As Nicole searches for answers, she uncovers a trail of deceit leading straight to the mysterious Glasshouse – a staggering palatial home constructed out of cut glass and icy granite, clinging to the hillside in a gravity defying show of power and wealth.

The day I was told I’d never be able to have a child, my world came crashing down. My husband says he still loves me, but I lie awake at night, wishing we could have a family. One morning, my husband’s side of the bed is cold and empty. I hear a noise and head downstairs. In the middle of the rug in my living room is a wooden drawer. Swaddled inside, with perfect rosy cheeks and beautiful round blue eyes, a baby gazes up at me.

They were destined to be best friends. The four girls – all born that same hot summer. They predicted a safe and happy life for them all…More than thirty years later, it’s more than an unbreakable friendship – it’s more like a sisterhood. It’s the girls who Jess reaches out to because she’s worried about her grandparents who’ve raised her since her mother disappeared, who Erin tells about her new business idea, who Melissa calls to say she’s desperate to escape her toxic job. But then Chantelle messages saying she’s discovered her husband is having an affair.

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.

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.

It’s my first day back at work, the grief I’m carrying is still with me, but I file it away and put on my professional face to greet my new patient. As a successful psychiatrist and criminologist, I’m used to working with damaged minds. But I’m not prepared for Trent Davis. Sitting across the table from me, his warm brown eyes shine. He laughs easily and part of me can't help but like him, despite what his file says he’s capable of. Then a package arrives for Trent, with my home as the return address. And everything falls apart…

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…

For Joel and Stella, it’s the trip they’ve been dreaming about. Fresh air, quiet time in the woods, and no work to distract them from each other. Being a new couple, they don’t waste any time with their first full weekend away together. But their perfect getaway turns into a nightmare when an accident occurs and they find a dead woman lying outside their cabin. Clearly, they have to call the police, but what Joel reveals to Stella makes her understand there’s no way they can get the authorities involved.

A bright and welcoming haven, the playgroup sits at the heart of the town, tucked away inside a red-brick building. The Nest should have been the safest place for my rosy-cheeked, pink-obsessed daughter, Florence. Run by mothers like me, I trusted my newfound friends–Alice, Beth and Georgie–to take care of my child. But now my choice has left Florence fighting for her life.

I’ve always longed to be a mother. So when my sister Sophia suddenly offers to be a surrogate for my husband Mark and I, it feels like our dream could finally come true. Sophia and I may have drifted apart, but tears of joy prick my eyes when I think about the precious, perfect gift she is giving us. And even though Mark is acting distant, I’m sure this will make us stronger than ever. When Sophia starts talking to us less and less I can’t help but worry… is it just like twenty years ago, when she disappeared from my life? Or will it be different now she’s carrying our miracle baby?

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.
