"I am always with you. I will always be here." This was the promise Ella’s mother betrayed thirty years ago when she walked into the sea, leaving her five-year-old daughter alone in the world. Ella’s been angry ever since, building up a wall to protect herself. But that all changes the day she opens a newspaper and finds those ten little words printed in a classified ad. Ella refuses to believe her mother could still be alive - that would mean she did want to live, just not with her daughter. So she throws herself into finding out exactly what happened all those years ago.

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....

All Linda wants to do is sleep. She won’t look at her husband. She can’t stand her daughter. And she doesn’t want to have this baby. Having this baby means moving on, and she just wants to go back to before. Before their family was torn apart, before the blame was placed. Alienated by their own guilt and struggling to cope, the Sadler family unravels. They grow up, grow apart, never talking about their terrible secret. That is until Linda’s daughter finds out she’s pregnant. Before she brings another Sadler into the world, Bea needs to know what happened twenty-five years ago.

When Charlotte McKay wakes up in a hospital bed with no memory of how she got there, all she wants is to go back to the perfect London flat she shares with her husband, and the impressive career she’s worked so hard to build. But something’s not right. Her husband David is at her bedside - but so is a three-year-old girl, and she’s calling Charlotte "Mummy"....

My one goal in life was to be a mother - to have a family - and in my little curly-haired Evie and my husband, Seb, I got everything I ever wanted. He and I trusted each other completely. There was only one thing Seb didn’t know about me - and if he ever found out, I knew that would be the end of our life together. Then the calls started. "You destroyed my life. Now I’m going to destroy yours." At first I hoped it was a prank. Then, I was terrified that the one person who knows my secret had found me.

Brooke is delighted when Oliver decides to rent her old family home with his three-year-old son, Finley. Finally someone to bring happiness to the run-down house across the street. They seem like the perfect tenants, but Brooke is a little unnerved when they move in with just a single bag between them. Where are their belongings? 

In the pretty, privileged college town of Milford, New Hampshire, everyone is friendly, and everything is safe. And on this cold autumn day, as red and yellow leaves begin to fall from the trees, and everyone wraps up for the first time, it would be easy to believe nothing bad could ever happen here. Until a screech of tires is heard, a thud, a child’s scream. The crash that sees Jenna’s six-year-old daughter, Amy Rose, being hit by a car driven by 17-year-old Maddie.

From behind the curtains, Sarah spotted the man coming out of the house, followed by the woman. It would be strange seeing people in the property. She wondered how much it would change their lives. For now, she would bide her time and hopefully get to know them better. She needed to gain their trust.

The white-washed Italian villa is perfect. I thought it might feel odd, living in a stranger’s house for the summer, but as my husband and children swim in the infinity pool, I start to relax. And then, in the back of a wardrobe, I find something that shatters everything.... Sparkling green eyes, square jaw, lopsided smile. A young man with his arm around a beautiful woman. The picture is old and faded, but I’d recognize him anywhere. The man is my husband.

Ever since Steph’s husband walked out after a 30-year marriage, home hasn’t felt like a safe haven. Her daughter Bea thinks she’s imagining things. But Steph knows that the noises in the night, the open windows she knows she left closed, the strange smell in the kitchen - none of it feels right.

Zoe didn't meet her daughter the way most mothers do. She finds five-year-old Maddie alone and dirty on a countryside road. Frightened for Maddie's safety, she picks her up and takes her back to her father, not knowing what she's about to step into. Because Maddie wasn't just lost; she was there to lure her serial killer dad's new victim. After escaping from the clutches of Maddie's dangerous father, she bonds with the little girl. Only Maddie knows what it was like to be at that house. And when no family members come forward to claim Maddie, Zoe decides to adopt her. 

Ever since we locked fingers and swore to be best friends at school, Sophie was there for me. When she married my brother, we became family. We laughed together and cried together. We never kept secrets from each other. At least, that was what I thought....

It’s the phone call every mother dreads. I’m climbing into the car after a trip to the grocery store. As the engine starts, my phone rings. It’s my stepdaughter, Shelby, who is babysitting my three-year-old Millie. "I only went upstairs for a second," she says through her sobs. "She’s gone." When the police turn up, Shelby’s story starts to unravel. What is she hiding? Then I get a message saying, "Your husband is not who you think he is." Suddenly, my family feel like strangers. Everyone has a secret - even me. 

I am cooking spaghetti, his favourite, while he plays in the garden. But when I look up, he’s gone. I call the police, my hands shaking so much that I hit the wrong digits twice. "My son is missing." When the police turn up, I’m trapped in the web of my lies. I have hidden the truth from eight-year-old Riley, my little boy who loves climbing trees and always has scraped knees. I have hidden my secret from everyone.

I waved my husband good-bye at the airport, and he vanished without a trace. I sat awake, night after night, looking at photos of our family. I knew he would never leave us. And then I found him. Now he lives with the younger, beautiful woman he thinks he loves. And he doesn’t even recognize me. Who will he choose? Can I forgive him? And will I ever be able to look into his eyes without thinking of his other woman?
