Marianne has a life others dream of. A beautiful townhouse on the best street in the neighbourhood. Three bright children who are her pride and joy. Sometimes her past still hurts: losing her mother early, growing up in foster care. But her husband, Simon, is always there. A successful surgeon, he’s the envy of every woman they’ve ever met. Flowers, gifts, trips to France: nothing is too good for his family. Then Simon says another woman’s name. The way he lingers on it, Caroline, gives Marianne a shudder of suspicion, but she knows it’s nothing - she can’t entertain this flash of paranoia.

It’s the day I’ve been dreaming about my whole life. As I glide down the flower-strewn aisle overlooking the Greek orange groves, in my pearl-encrusted ivory gown, I finally see my fiancé Nik. We look like the perfect couple, but not all fairy tales have happy endings....

Clare is ready for a break. It's been a tough year and now she wants to put her feet up. Arriving at the Italian villa for their summer holiday, she decides it's high time her husband and his family did some of the work. After all, her husband owes her.... Now her brother-in-law Jamie has brought a wife, someone none of them have met before. Ella is everything Clare isn't. Glamorous. Young. Influential. But she knows a secret about Clare. Something that has the power to break the whole family apart.

Then: Morning light shines into the nursery, casting shadows across the pale pink walls and wooden cot in the middle of the room. She opens the door expecting to hear the soft coo of her daughter, Sofia, stretching herself awake. But the room is silent. The cot is empty. Her little girl has vanished. Now: Twelve years have passed, but Emily will never forget the night her life changed forever, and she’s happy to have her daughter back beside her. A teenager now, Sofia started asking questions about when she was a baby.

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.

You’ve been excited about this getaway for months–at last, a chance to reconnect with your husband at a secluded island resort. But when he unexpectedly calls you from the beach, you hear the urgency in his voice. Something is very wrong. The beautiful waitress from the restaurant last night has been found lying dead in the sand. And the police want to question your husband about it. Sure, you saw him glance at her over dinner a few times, but you know he didn’t have anything to do with the poor girl’s death. 

Hannah has done everything to make sure her life is safe and secure. A long way from her unstable childhood growing up in foster care, she’s content with her sweet, little, messy apartment and her satisfying job as a social worker. She quietly worries that, aged 36, she might never fall in love. But otherwise her life is where she wants it to be. Until, encouraged by her best friend to join a dating app, she meets Alex. He’s irresistibly handsome. He loves the same music as her. The same food as well.

Lucy has a kind and adoring husband, a job she loves as a teacher, and a house on Mulberry Avenue with floaty curtains and the softest bed linen. After her troubled childhood, she knows life will never be perfect, but it’s pretty close. She’s also got Amber, right next door. They never run out of things to talk about. Even if Amber’s life - with her high-profile job and handsome, wealthy boyfriend - is more glamorous than Lucy’s, they share a down-to-earth sense of humor. But then Amber starts to hint that her life isn’t all it seems....

My darling son, Sam, is marrying his childhood sweetheart, and I couldn’t be prouder of the man he’s grown into. Walking out on his abusive father all those years ago was the best thing I ever did. And today he stands, tall and handsome, saying "I do" to my dream daughter-in-law. If I hadn’t pushed them together all those years ago, he might never have found a girl as perfect as Lauren. It’s true what they say, mother always knows best. 

From the moment I meet my new mother-in-law in her beautiful country house, she makes it clear I’m not welcome. Lilian Fletcher hates me for marrying her precious boy on a golden beach far away from her. Starting our marriage living in the Fletchers’ family home is a nightmare. Then I discover Seb was married before and his first wife is dead. I wonder why the man I love didn’t tell me the truth. And I wonder what happened to her: the woman who came before me. How did she die?

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.

Kirstie Rawlings is jolted awake by a child crying. Racing upstairs to check on her newborn, she is plunged into every parents’ worst nightmare. She hears an unknown voice in the baby monitor, saying: "Let’s take the child - and go." Is someone trying to steal her little girl? In the bedroom, her daughter is safe asleep in her cot. Is the voice coming from a nearby house? But there aren’t any other children living on her quiet country road....

The doorbell rings, just days after my beloved husband’s sudden death. I don’t recognise the woman on our doorstep, with her blonde highlights, a diamond bracelet identical to my own and a bouncing baby boy in her arms. As I show her inside, I notice her eyes grow wide as she takes in our spacious hallway, and the big squashy sofas that we all used to pile on. She glances at the silver-framed family photos and my little daughter hiding behind my skirts. She looks at me, her blue eyes serious. ‘I’m sorry’ she says. ‘I am your husband’s girlfriend. And this is his son.'

Ava only left her daughter in the pushchair for five minutes. The buckle was fastened, and she was sure it was safe. But when she came downstairs, the door was open and Abi was gone - she walked down the road, past the Lovegoods' house, and was never seen again. A year later, the Lovegoods throw a housewarming party, showing off the results of their renovation. Ava doesn’t want to go. She can’t bear to look down that end of the road, to see the place where Abi vanished, and she doesn’t want to spend time with people who don’t share her grief. 

Two-and-a-half-year-old Holly is playing happily in a pink, plastic playhouse, while her mother Rachel sips coffee and chats with a friend nearby. It should be an ordinary day for all of them. But, in the blink of an eye, it turns into every family’s worst nightmare. Holly is taken by a stranger and never found. Nine years later, Rachel is living a quiet life in Dorset. She’s tried to keep things together since the traumatic day when she lost her eldest daughter.
