Everything changes when Mark comes home from a work trip with dark circles under his eyes. The police want to question him about the murder of a beautiful, blonde young woman. Mark swears he had nothing to do with it, that she was a colleague, nothing more.

I glance over at Lou’s house as I pull onto my drive, surprised that it is still in darkness. Lou and the kids should have been home from school long ago. I should be preparing a delicious meal for my children as they tell me about their day. But Lou’s car is nowhere to be seen....

The call came on a seemingly ordinary day. But as soon as Rachel heard the pain in her sister’s voice, she had to face the fact that life as she knew it was about to be shattered: “It’s mum. She’s not well. She doesn’t have much time.” Though her heart breaks to leave her husband and children behind, Rachel knows the right thing is to return home to care for her mother, Janet. Their relationship has been strained for years. This may be the last chance for them both to heal.

"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.

Ali turned towards the cottage, anger flooding through her. She’d believed she and Meg were friends; that they’d bonded over a vision of motherhood...a world where your baby deserved everything you could give it. She’d pulled Meg’s words - Meg’s life - around her, like a comfort blanket. But that shared vision had never existed. And Ali was alone now, with nothing to protect her.

Two days ago, the Wilson family checked into the imposing, glass-fronted Lodge, surrounded by snow and perched perilously on the edge of a cliff looking out to a gray sea. Not everyone was looking forward to the family get-together. But mother-in-law Angela insisted the winter trip would help heal their rifts....

From the outside, my marriage to Zach was perfect: a dream home, a perfect baby girl, and passionate, all-consuming love. But as I cradle my gorgeous baby, I have to accept that the husband who used to be my everything has changed. At first, it was little things: expecting me to keep to a strict schedule, picking out my clothes for me. Now, he controls every aspect of my life: from how much money I have, to when I leave the house, and who I can see. I know deep down, only one of us will make it out of this marriage alive.

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....

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.

Of course, I’m not going to murder her in the night. I need my laptop back first. That’s the whole point of making friends with Emily Harper, author of the hugely successful novel Diary of an Octopus. So I could get into her apartment and take back what’s mine. Emily doesn’t know who I really am. She thinks I’m her biggest fan, her new best friend who happens to need a place to stay for a few days. She doesn’t realize the laptop she found—and took—from a busy airport almost two years ago was mine. I don’t care about the laptop, just what's on it: my diary.

Leah and her three best friends get changed into their pyjamas, eat pizza, and argue about what film to watch. They laugh together, until the early hours. But the next morning, Leah blinks open her eyes and sees three empty sleeping bags. The other girls are gone. Twenty years later. In her small hometown, still-haunted Leah has never been able to shake off the rumours and whispers. How could she have slept through it all? She must know what happened.

Elodie Fray wants to be more like her perfect sister, Ada, the one her parents are actually proud of. When she decided to quit her job and pursue her dream of becoming an author, she thought it would be her time to shine, but a year on nothing has happened. And she's getting desperate. When Elodie makes one small mistake on a drunken night with a friend, things quickly spiral and suddenly everyone believes she has a book deal. Unable to find a way back from her little lie, her perfect dream becomes a perfect nightmare - and desperate times call for desperate measures.

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.

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.'

Callie was living in a ten-acre home in the stunning Adirondacks with her husband. She missed her son, who was away at college, but she was coping pretty well with her empty nest. Then, the nightmare began. Her husband Abel skidded off the road into an icy lake. His truck hit a tree and plunged into the frigid water below. Now, this once-vital 43-year-old carpenter lies in a coma, surrounded by bleeping machines and the hushed rumble of the ward at Pearl Medical Center in Vermont. The police say it was an accident, but the details remain murky.
