It is past 10 o’clock on a cold Friday night when Rebecca and her husband Jack’s doorbell rings. Outside is a woman who introduces herself as Jack’s ex-girlfriend, Cara. And she’s holding the hand of a shivering, blue-eyed, four-year-old girl who she claims is Jack’s daughter. Rebecca is shocked to discover he has a child from his last relationship - even one he hadn’t known about. Because becoming parents isn’t part of their life plan.

When Emily’s husband dies in a terrible accident, she’s not the only wife he leaves behind. Before their whirlwind romance and Emily’s discovery she was pregnant, Pete had been married to Caroline for more than 20 years. A devastating tragedy had torn them apart. But there was a part of Pete that had never fully left his first wife and a secret that would bind them together, forever. Finding herself lonely, heartbroken, and forced to face life and motherhood alone, Emily knows she needs someone she can trust and rely on. Even if it’s the woman her husband loved before her. 

Ever since Ruby was tiny, she has been unique. Her smiles are magically rare, and she likes things done in a very particular way - her blocks are always color-coded, and her toy animals stand in regimented lines. She’s also the daughter of Sara’s dreams - even on days when being a mother to a three-year-old is exhausting. Not everyone understands Ruby like Sara does though. Not Sara’s husband Mike, and certainly not her disapproving mother-in-law, Barbara. So when circumstances force their family to move in with Barbara, Sara knows it’s going to make motherhood even harder. 

When I was a kid and I’d lost something, my dad always said, ‘Go back to the place you last had it’. The problem is that what I’ve lost is...me. Kate loves her family more than anything, but recently she has started to feel invisible.

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.

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.

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....

When I was young, my friend Sarah and I did a terrible thing - but it was only me who paid the price. Now, just when I thought no one from my old life would ever find me, a note slides under my door: "I haven’t forgotten. I haven’t forgiven. FOUND YOU."

Then, one day, as they pick at sandwiches in a crowded local café, a beautiful girl approaches, claiming to be Sara. With her wide green eyes and soft, straight hair, could she really be their long-lost girl? But where has she been all this time?

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.
