When six-year-old Olivia Adams disappeared from her back garden, the small community of Stoneridge was thrown into turmoil. How could a child vanish in the middle of a cozy English village? Thirteen years on and Olivia is back. Her mother is convinced it's her but not everyone is sure. If this is the missing girl, then where has she been - and what happened to her on that sunny afternoon? If she's an imposter, then who would be bold enough to try to fool a child's own mother - and why?

Seven-year-old Beatrice has gone missing. Her mother Claire’s whole world has been turned upside down in just one moment, and she can’t stop shaking. She’s desperate to find her precious daughter, but nothing about the day she disappeared makes sense.

Tucking her little boy Ollie into bed one night, Sarah notices his beloved teddy bear, which she bought him when he was born, is missing and in its place is a new toy given to him by her ex-husband’s new girlfriend, Laura. When she asks Ollie about it, he begins to shift uncomfortably before whispering, "Laura told me a big secret, and she said I can never tell you." Soon, Ollie is asking to spend more time with his dad and Laura, and shrinking away from Sarah. Then, when she calls to him in the garden one day, Ollie doesn’t answer back. 

Ten years ago he killed my son. Today I married him. Ten years ago my darling son Jesse was murdered and our perfect family was destroyed. My strong, handsome boy, so full of life, became a memory, a photo I carried with me everywhere. But today I’m finally close to finding happiness again. My ash-blonde hair has been curled into ringlets. Carefully placed white flowers frame my delicate features. The small, drab chapel has been prettied up with white satin, and there are tiny red hearts scattered on the small table where I will soon sign the register with my new husband. 

I return home to our beautiful house on a chilly winter evening expecting to find my handsome husband Richard waiting for me by the fire. We’re still so in love, and he always takes care of me. He usually comes straight back from work. But tonight, our antique clock ticks on through the dark evening, with no sign of him. Then a knock at the door shatters my perfect life. A 12-year-old-girl, Alice from the village, has been found unconscious in the field behind our house. They say she was last seen getting into Richard’s car.

Our new home was supposed to be a chance to leave our past behind. But was moving here the worst mistake of our lives? All our friends and family were gathered, glasses raised to toast our fresh start. It should have been a night for happiness and celebration. Zac and I had worked so hard for this: our first home together, just minutes from the sea. But the dream quickly turned into a nightmare.

I wrap my arms around the tree trunk, pressing my cheek against it until the bark digs in and the missing poster is finally secured. I try not to look at the photograph on it. At the features so similar to mine. Perhaps this will be the year someone comes forward. Were crucial mistakes made by detectives from the very beginning? Could the pressure of living two lives have led my sister to run away - or even end it? Or did someone in her tight circle of friends and family have reason to want her gone? Someone out there must know something. 

Shelby Tebow is the first to go missing. Not long after, Meredith Dickey and her six-year-old daughter, Delilah, vanish just blocks away from where Shelby was last seen, striking fear into their once-peaceful community. Are these incidents connected? After an elusive search that yields more questions than answers, the case eventually goes cold. Now, 11 years later, Delilah shockingly returns. Everyone wants to know what happened to her, but no one is prepared for what they'll find....

For 15 years, Lexi and Jake have played the same six numbers with their friends. Over drinks, dinner parties and summer barbecues, the three couples have discussed the important stuff — kids, marriages, careers — and they’ve laughed off their disappointment when they failed to win anything.

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven. 

What was my sister doing standing over Florence’s cot in the middle of the night?I trust my sister, Carrie, with my daughter’s life. But then she’s accused of a terrible crime. Carrie lives under our roof, she pushes my daughter on the swings, she takes her out for ice cream. You might ask, why do I let her? Why would I risk my darling baby? How could I let my sister stay? Because I have a dangerous secret too. One that only Carrie knows about. And if that secret gets out, I could lose my little girl....

I nearly threw the letter about the inheritance away with the recycling. Late for work, worrying about how I would afford new school shoes for Kate, I just assumed it was a mistake. But perhaps moving to a new home in a quiet seaside town would be the fresh start we both need. Away from the school bullies making Kate’s life a misery, and out of the clutches of my dangerous ex. 

I made a new friend at playgroup today. She’s different from the other mothers. She feels like someone I can trust. Someone I can confide in. But there are some things I can’t tell her. Things I can’t tell anyone. Because I have a secret that no one else knows. One that still haunts my dreams, wakes me up in cold sweat at night. Even another mother would never understand. Unless, of course, she’s hiding something, too.

Just four words were printed in the card. He doesn’t love you. I’ve been dreaming about this day - marrying Adam, my childhood sweetheart, who I’ve loved for 18 years. I didn’t realize the perfect day would turn into the perfect nightmare. I was so excited to send out the wedding invitations, carefully writing everyone’s names on thick cream paper in beautiful cursive script. I had no idea I was inviting someone to destroy our marriage. 

Emily and Jake are the perfect couple. Or so everyone says. But Emily just read a letter that has shattered her perfect world. Now she only has one thing on her mind. Which one of her friends is sleeping with her husband?
