Charlie takes my breath away from the moment we meet, when he is dropping his adorable little girls off at the school gates at the same time as I’m waving goodbye to my son. Being a single mother has been hard. So when his gorgeous green-blue eyes hold mine and his lips curve into a smile I wonder if this is my chance to find happiness and escape the secrets in my past.

I take a sip of coffee as I plan my day. My surgeon husband, Cole, slept at work last night, so I had to get the kids ready on my own, again. I can’t complain, though, I’ve loved him ever since we met, long before he became a famous surgeon and the papers started calling him the pride of the hospital. Our latest family photo hangs on the kitchen wall and I remember that day so clearly. Cole screamed at me over nothing, then apologised saying he was stressed at work. My heart pounded with fear, but I plastered a smile on my face for the sake of my children.

On the last day of school, my friends and I gather on the beach to celebrate the long summer ahead. Sipping cans of warm cider and watching campfire embers dance into the inky sky, I don’t think I’ve ever been happier. Until a scream pierces the night. The next morning, we find shy newcomer Pippa on the beach, sandflies gathering on her lifeless body…

How well do you really know your own family? The wife: Eve is desperate for her life to be perfect. Living in a beautiful house, with gorgeous views of the countryside, is all she’s ever wanted. And she’ll do whatever it takes to hold onto her dream life. The son: Joe is a model student; he never puts a foot wrong. He knows his mother wouldn’t tolerate it. Until the night of his sixteenth birthday party, when things go horribly wrong and someone in the house is left fighting for their life. As the blue flashing lights of the police and ambulance arrive, all eyes are on the Griffiths family.

I thought my first husband died ten years ago. But now he’s back... Opening the front door, I’m stunned to see a familiar face. I never thought I’d see Freddie’s deep brown eyes and crooked smile again. But how is this possible when he died ten years ago…? It took years to move on, but finally my life is almost perfect.

I used to enjoy my job. I was good at it and felt fulfilled. I also used to enjoy spending time with the people I worked with. They say you spend more time with your work colleagues than you do with your family members, but that was fine by me because I made two very good friends at the office. I also allowed myself to get a little too close to my boss, but I soon realized that was a mistake. Unfortunately, it was too late by then, and as my personal and professional lives quickly blurred into one, that was when everything changed.

Wife: I couldn’t be prouder of my charming husband and quiet and kind son. I’ve poured everything into my little family, so I choose to ignore my husband’s late-night phone calls and wandering eye. I won’t let anything ruin my perfect life…

I’ve fallen in love with a man called Sam. And he’s perfect, just perfect. It’s a whirlwind romance. And when our dream home falls through just before our wedding, we decide to move in with his parents. He says his mother, Evelyn, is the sweetest person. But I’m not so sure. She’s obsessively protective over Sam. She wants to know where he is all the time. She wakes us up in the morning, bustling into our room like he’s a small child, not a grown man. She doesn’t want me to be alone with him.

Some secrets refuse to stay buried... Abandoned by her mother, Lucy Mitchell grew up in foster care, where she found solace in her best friends, Amber and Josh. In a strict foster home, Lucy and Amber made a pact – friends for life – often escaping to the woods to hide from their overbearing carer, Linda. Then, one day, only one of them comes back. Amber was gone, leaving behind only a note: I’ve run away. Fifteen years later, Lucy is planning her dream wedding to Josh – until a body is discovered.

I thought he was dead. Until I saw him staring back at me… Ten years have passed since my beloved sister was murdered, leaving behind her sweet five-year-old daughter, Lily. I’m trying my best to care for Lily and salvage what’s left of our shattered family. I promised to keep her safe after all she’s been through, and after a lot of challenges, I hope she might be starting to lead a normal life again. But then I see a face in a photo I took just yesterday that turns my blood to ice.

Caroline twitches aside her curtains to see the new family moving in. A mother – beautifully dressed in expensive clothes – and two young children. Where is her husband, she wonders? And why are they moving in to the smallest house on the street? They really don’t seem the type. But Caroline believes it’s important to be welcoming. It’s important to know everything that’s happening on West Street.

Emily has the perfect life. The perfect husband. The perfect daughter. But she also has the perfect secret. One that could destroy everything she holds dear... one that could ruin her.

When I first meet Sophie, she seems like any normal loving mother, trying desperately to help her teenage daughter. That’s where I come in. The perfect tutor to get Katie’s life back on track. I connect instantly with Katie, and Sophie’s thoughtful husband Scott. But Sophie’s dark eyes are full of jealousy when I talk to Scott or share a smile with Katie. I know I’m helping her daughter, whatever she thinks.

Pete never wanted another child. Before baby Erin was born, they were happy. If Natalie hadn't got pregnant, he would never have done what he did. Natalie knows things have been difficult since the surprise arrival of Erin. Life with Pete and their two other children—Emily and Zadie—has been balancing on a knife-edge. Now their home is full of guests at a party Natalie didn't want to throw—and she's about to reach breaking point. But so is her family. Because everyone has a secret that they've been hiding and when Erin suddenly disappears everyone becomes a suspect.

ME: Staring down at the sweet baby in my arms, I feel panic instead of love. Because this isn’t the child I gave birth to. My husband whispers to the midwife. They all think I’m going crazy. But the tiny boy in my arms is crying again. I’m certain: he knows I’m not his mummy. And I’ll do whatever it takes to get my son back.
