It’s a normal afternoon when I walk out the patio doors of our kitchen to check on Mia, my stepdaughter, who is swimming in our backyard pool. But she’s gone. My heart stops when I see the back gate is open, her pink, fluffy towel lying folded on a chair. I was just feet away. Why didn’t I hear her scream? Who took our little girl?

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....

My darling little boy Albie adores playing at our new neighbours’ house. And after the terrible year we’ve had, I feel so lucky that we can start over in this perfect place, with new friends who treat Albie like the son they never had. He can’t stop talking about the tree house they’re building him, and the cookies they bake together. But as time passes, something starts to feel wrong. Why don’t they ever open the front door more than a crack? They told me they had no children so who does the small pink tricycle I saw in their hall belong to?

When Sarah Larsen finds the notice, posted on creamy card stock in her building’s lobby, one glance at the exclusive address tells her she’s found her ticket out of a dead-end job - and life. At the interview, the job seems like a dream come true: a glamorous penthouse apartment on the Upper West Side of NYC; a salary that adds several zeroes to her current income; the beautiful, worldly mother of her charge, who feels more like a friend than a potential boss. She’s overjoyed when they offer her the position and signs the NDA without a second thought.

Taking a deep breath of the fresh, leafy air, Abigail promises herself: Today she is going to make her parents accept her future husband Pete’s family. She’s planned three days away from it all in a beautiful, forested nature reserve. Out here, with almost no one else around, their families will have nowhere to run. They might have clashed from the moment they met—with their stark differences in backgrounds and personalities—but now, Abigail thinks, they will have to get along.

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?

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?

When I accepted a job working as a nanny for David and Julie and their young children, I was excited to be making my own way in the world. I bonded with baby Chloe instantly and would have done anything for her. She had David's thick, dark hair and smiling eyes. I fell in love with her and was excited for my future. But when a terrible mistake led to Chloe disappearing, I was instantly blamed. With no evidence, I was let go and I returned home to rebuild my life. Twenty years later and I am still haunted by what happened.

Pulling a batch of my husband’s favorite golden oatmeal cookies from the oven, I smile to hear my daughter Phoebe playing in the treehouse outside. I was once so close to losing everything, but since I married handsome Jackson, I have a perfect life. Jackson might tell me what to wear, but he just likes to buy me nice things. He says I don’t need a job, and why would I want one? I can spend all day taking care of Phoebe and running errands in the fancy car Jackson gave me—he knows everywhere I go. But my whole world shatters when I find out Jackson is a liar.

Today we move into our new houses, right next door to each other. My ex-husband and me. He’s with someone else. So am I. We’re still the best of friends. We’re making sure we’re not like every other separating couple. We know we will make it work. We’ve even knocked down the fences between the houses, so the children can all run between both homes. But it seems not everyone likes this big, blended stepfamily. I try to ignore the scary note in the "new home" card and the red pen scrawled through my divorce paperwork.

Everyone in the small Midwestern town of Henderson looks up to my perfect parents. With dependable jobs as a midwife and the town sheriff, they help this close-knit community feel safe. But the locals didn’t grow up in my parents’ house. They don’t know what I know. And they wouldn’t believe me if I told them....

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.
