Alice has everything, I mean everything. A stunning suburban house, Instagram-perfect in its soft grey walls and textured neutrals. And then there's her handsome husband, with his flat stomach and that sexy sleeve of tattoos he keeps hidden for his well-paid job in the city. The PTA mamas can't stop staring at him, and who can blame them? And let's not forget her three adorable, well-behaved children. Meanwhile, here in Boston, I'm struggling to start a family with my husband Ollie. Our marriage is suffering, and I feel so isolated all the time.

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....

I gaze at my new husband and smile. It’s our wedding day and I feel like the luckiest woman alive. Lucas is perfect. He brings me coffee in the morning, flowers in the evening, and never leaves the room without a kiss.

I open the creaking oak front door of my beautiful country house to see a stranger on my doorstep. The woman is stunning with glossy red hair and flawless make up. "Can I help you?" I ask. That was my first mistake. Alexis tells me she is a distant relative and shows me a DNA match on her phone. She has no family and would love to get to know us. My husband Hugh invites her in to join our dinner party. As we drink wine, she opens up about her sad childhood. Her amber eyes are mesmerizing, and I can see my husband is being drawn in by her story. Then she asks for our help.

‘I’m sorry, Sam’s not available,’ says the woman who answers my husband’s phone. I can’t place her voice, so I politely ask who she is. Her answer sends my world spinning out of control: ‘I’m his wife.’

It was meant to be Caitlin's perfect summer, but betrayed by her best friend and her boyfriend, she finds herself hitchhiking home alone, heartbroken, and penniless. When a smiling family pulls up on the roadside to help her on her way, she's relieved at first - they seem friendly, normal. And when they offer her a warm bed in their cottage for the night, she's grateful - it's not safe for young women travelling alone in the dark, and she's in no rush to get home, where she knows a grave secret is due to blow her family apart.

I stand in the mortuary and take a deep breath before identifying the body of the man I’ve been married to for 26 years. Victor and I built Serenity Falls, a successful couples’ retreat, together. Honesty and trust were the bedrocks of our marriage, and we helped other couples repair their relationships too.

A man jumps into your car and tells you to drive. He’ll kill you if you disobey. But you have somewhere to be. A secret to hide. All those years back, it nearly destroyed your family. You can’t let that happen. But no matter what you do, someone will die tonight. And then who will they believe?

In the wake of my darling husband’s death, I am so lucky to have my three beautiful, grown-up daughters by my side at our holiday home in Scotland. We need some time together to recover from the shock. But I also need to set some things straight about their beloved father....

My husband is a doctor. He’s smart and charming, and everybody trusts him. Except me. On the surface, it looks like I have it all–the perfect marriage, the perfect husband, the perfect life. But it’s far from the truth. Doctor Drew Devlin is not the respectable figure he makes out to be. The reason we moved to this beautiful, old property with a gorgeous view of the sea was because we needed to put our past behind us. It should’ve been a fresh start for us both.

Jake and I were childhood sweethearts. Strong, dependable, and with a smile that melts my heart, he is the perfect husband and father to our beautiful little daughter. We have our money troubles–but getting a lodger, Kara, calms the panic I feel about our bills. Jake is reluctant but what choice do we have?

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.

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.

I gaze at my husband’s once handsome face, so still and pale in the hospital bed. The doctors say I should keep talking. He might be able to hear me even after the terrible accident that left him fighting for his life. But all I have to whisper to my husband is this: "I know what you did."

In a windswept British seaside town, single mum Alice Lake finds a man sitting on the beach outside her house. He has no name and no idea how he got there. Against her better judgment, she invites him inside. Meanwhile, in a suburb of London, 21-year-old Lily Monrose has been married for only three weeks. When her husband fails to come home from work one night, she is left alone in a place where she knows no one and with the police telling her that her husband never existed.
