My husband and I are the dream couple: deeply in love, the envy of all our friends and neighbors. He surprises me with flowers; I make him his favorite meals and prepare picnics to enjoy with our son. It’s little gestures like this that keep our romance alive. But nobody knows how frightened I am at night. Oliver promises he’ll keep me safe, but I can’t stop feeling like someone from my past is watching me. Coming for me. I could have sworn I saw someone watching me through the window, lurking in the shadows across the street.

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....

A forged reference and a fake social media page is all it takes to convince the Mayers I’m the perfect person to look after their son Wyatt. Some people would be scared to move to a remote mountain village with a family they’ve never met, but it’s exactly where I need to be. Because Wyatt is my child....

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?

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.

It’s hard meeting your ex after so much time apart. You remember the tears and accusations, the desperate look on his face as he punched the wall, but you try not to show it. You smile politely, even while your heart beats faster. You watch as he looks down into the stroller, at the beautiful blond-haired, blue-eyed baby kicking his little legs in the sunshine, whose innocent smile lights up your world. You see his face change. You know what he’s thinking. The next day he calls. His voice is shaking. He wants the truth. Is it his child?

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.

Long blonde hair. Sparkling dark eyes. Perfect pearly white teeth. I’ve never met her before, but I know exactly who she is as I spot her through the crowds of the terminal. Because our new guest is the spitting image of the daughter we lost. And that’s exactly why I chose her.

Her chest tightens, her heart speeding up. The kitchen is chaos. She steps on something hard, and looks down. Toy dinosaurs are scattered everywhere. But her son is nowhere–her baby boy is gone.

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.

Cate grips the note with trembling hands, looking down at the delicate bundle on her doorstep. As she reaches down to the baby, she knows she has finally got everything she’s ever wished for. But is he hers to take? Cate tries not to cry as she closes the door on the nursery room once again. All she has ever wanted is to be a mother. Cursed with a medical condition that means she is unable to have children, her only option is to wait for a call from the adoption center. But that call feels like a lifetime away.

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.

Elizabeth is Joe’s foster mother, but she loves him like her own. The five-year-old, who adores superheroes and watching the birds outside, is the child she has dreamed of. As she looks into the garden, where he was playing just moments ago, her heart feels like it has been ripped from her chest. She was meant to save Joe from his birth mother who almost harmed his chances at life. The woman who has been trying to desperately get him back. She was meant to protect Joe from her husband. The man who, right now, lies to the police, saying he was making breakfast when Joe disappeared.

Becoming a stepmother is the best thing that ever happened to me. My favorite part of every day is picking Charlie up from school, watching her little rucksack bounce behind her as she skips over for a hug. I love the feel of those thin freckled arms around my waist. After a few rocky months of panic attacks when her mother deserted her, Charlie is flourishing. But the day Charlie’s mother Bronwyn returns without warning—showering Charlie with gifts and making promises she can’t keep—fear ripples through me. She doesn’t know just how far I will go to protect that little girl.

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.
