Last night, we celebrated our anniversary. Over candlelight, we talked about the children, our work, and I was so happy, and felt so loved. But the next morning, when I check my phone, there is a message. From a friend. And a string of photos appear of my husband, Will, with another woman: walking along the street holding hands. Going into fancy hotels. Standing at a window, his arms around her, her head on his shoulder…

I could tell when my son started hiding things from me. He used to walk to school with a mischievous grin on his beautiful face. Now he avoids eye contact and keeps his head down. Since I discovered he’s being bullied by a classmate, I’ve spent every day worrying, my stomach churning with anxiety from the moment he leaves the house to the second he walks back through the door. Everyone keeps telling me I’m overreacting, but I won’t risk my child’s safety. My husband and I try to talk to the other boy’s parents, but it only makes things worse. Then our precious child is hurt. Enough is enough.

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....

When I first walked into Jake and Megan’s immaculate home, I felt totally at ease. Sitting in the crisp white living room, they held hands and talked lovingly about their baby girl, Fern. As the weeks passed, I began to think I’d made a mistake in taking the job. Jake was overly friendly from the start, watching my every move and always offering to drop me home, even though it was out of his way. And Megan seemed to take pleasure in telling me off in front of her husband, blaming me for things I hadn’t done.

When Mel arrives at the holiday cottage in the Lake District, she expects to find the heating on and her husband Luke and the two children waiting for her. Maybe a bottle of wine open… Instead, there is just a note on the side, saying they’ve gone out for a walk. But they aren’t back several hours later, and Mel knows something is wrong. Really wrong. When a search doesn’t find them, she has to confess to the police that her marriage isn’t all that it seems.

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.

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.

I’ve been on edge the whole time because 15 years ago when we were living in this city my husband Jack did something that ripped our lives apart. I swore I would never come back here, but Jack insisted. One afternoon, in the blur of a crowd, I lose sight of my son. I can’t find him anywhere. Frantic, I call my husband. But what he tells me next shakes me to the core....

Sara made one promise to herself when she was growing up in foster care: that if she was lucky enough to have a family, she’d always do whatever it took to protect them. Looking around her home with its cozy kitchen and living room, where her energetic teenage daughters and gorgeous 4-year-old son all eat, play and live together, she knows she’d do anything to keep them safe. So when Sara’s husband Matt loses his job and every shred of his confidence with it, she knows it’s up to her to bring the family back from the brink.

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....
