Melody gazes across the rippling lake to the trees on the shore, waiting for her fiancé Evan to arrive so their family holiday can begin. Here in this cabin in a small Canadian island town, there’s so much space for their son to play. It’s going to be perfect–just like the first time Melody visited as a child. But then, a call from Evan shatters her world.

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.

It feels like all the air has been knocked out of me. My best friend is dead, killed at her own daughter’s birthday party. All I want to do is run into my husband’s loving arms. But he’s in handcuffs, covered in her blood. His voice quivers, almost sobbing as officers put him in the police car. ‘You don’t think I did this, do you? I was trying to save her.’ At first, I’m sure he couldn’t have done it. The man I love wouldn’t hurt anyone. But as I try to prove that he didn’t murder Lucy, secrets begin unravelling…

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.

Hannah Parker is a woman who always gets what she wants. When her current husband discovers she has been lying to him – again - she knows it’s time to move on and find someone who can give her the life she desires… The life she knows she deserves. But who will be the lucky man? When her eye catches a glimpse of an old flame in a photograph, she’s sure it’s a sign.

I know Benjamin’s new business is in trouble, that he desperately needs your money. I saw the way Gwyn looked at him at your wedding reception, finding any excuse to be close, to laugh too loudly at his jokes. After all, she always wanted your perfect life. But don’t worry, Madeline. I won’t let it end like this. I can see everything from my place in the shadows between the trees. With their house lit up, they are on display. I’ll bide my time and worm my way into their home, their lives. They will never know the truth about who I am.

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.

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 thought handsome, charming Blake would be the perfect fit for my quiet and sweet-natured friend Melanie. Widowed far too young, she deserved a second chance at love. So, when he proposed so soon after I set them up on a date, I convinced myself that the timing was just right. But I should have stopped it. I tried to ignore Blake’s controlling behavior. It started small; telling her not to have a glass of champagne to celebrate their engagement, putting cameras up around her house for “safety”. But Mel seemed so happy and in love, I couldn’t bring myself to share my creeping doubts.

My mother is obsessed with every detail of my wedding–controlling my dress, my ring, my happiness. But when the day finally comes, will she really let me go?

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…

When Ellie tells me she has a new boyfriend, I am absolutely thrilled and can’t wait to meet him. She finally seems so happy and in love. But there’s a catch. Ellie has never met him in person. In fact, he doesn’t even live in the same country. Our home is in England, but Daryl is in Los Angeles.

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?

I could tell when my son started hiding things from me. He used to walk to school with a mischievous grin on his beautiful face. Now he avoids eye contact and keeps his head down. Since I discovered he’s being bullied by a classmate, I’ve spent every day worrying, my stomach churning with anxiety from the moment he leaves the house to the second he walks back through the door. Everyone keeps telling me I’m overreacting, but I won’t risk my child’s safety. My husband and I try to talk to the other boy’s parents, but it only makes things worse. Then our precious child is hurt. Enough is enough.

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?
