From the outside, my marriage to Zach was perfect: a dream home, a perfect baby girl, and passionate, all-consuming love. But as I cradle my gorgeous baby, I have to accept that the husband who used to be my everything has changed. At first, it was little things: expecting me to keep to a strict schedule, picking out my clothes for me. Now, he controls every aspect of my life: from how much money I have, to when I leave the house, and who I can see. I know deep down, only one of us will make it out of this marriage alive. 

Three years ago, nurse Zoe's son Ethan was found drowned in a muddy river by their home, along with his best friend, Josh. With no witnesses, their deaths were ruled a tragic accident. Heartbroken, Zoe and her family move away from her home. They’re just beginning to get back to some kind of normality when, out of the blue, Zoe receives an anonymous email: "You need to find out the truth about what happened to your son. Don’t let this rest. Don’t believe the lie." Shaken, Zoe starts an obsessive hunt for the truth.

My best friend warned me that it was too soon to marry Edward, a widower with an adorable but troubled little boy. She said we were moving too fast. But all I could see was a kind, loving man, struggling with grief, who needed my help. Yet as storm clouds gather above our small wedding ceremony, my hopes and dreams fall apart. None of my husband’s family turns up to support us. Instead of a honeymoon, we have a quiet night in. My wedding bouquet is placed on his first wife’s grave. And then my new stepson tells me he’s sure his mother is still alive.

Eve wanted nothing more than to be a mother. She and her husband, Aidan, planned to have a family, but with each devastating miscarriage her hopes dwindled. When she eventually gave birth to her daughter, Kayla, it should have been the happiest time of her life. Instead, it was a waking nightmare for Eve and one she was desperate to escape. Now, Eve has left all that behind. She pretends that she never had a child and keeps her secrets close. But someone knows the truth. They know that Eve told a lie, and the clock is ticking before her shocking decision is revealed. 

Tara Logan adores her perfect little family: husband, Noah, and two children, teenager Rosie and 11-year-old Spencer. But her happiness is shattered when she wakes in her neighbour Lee Jacobs' bed, with no memory of how she got there or what happened between them. And worse - he has been stabbed to death. Convinced she didn't kill Lee, Tara flees home and stays silent, holding her breath as the investigation grips the neighbourhood.

Mia Hamilton lived the perfect life with her husband, university teacher Zach, and their two-year-old daughter. But everything changed when Zach committed suicide on the same night one of his students vanished. Five years later, just when Mia is beginning to heal, stranger Alison walks into her life, saying her husband didn't kill himself. Fragile, slight Alison leads Mia on a path into Zach's past, and Mia begins to think she never really knew her own husband.

Staring at the stunning diamond solitaire on her finger, Kaitlin is finally getting the chance to introduce her best friend, Zoe, to her perfect fiancé. She hasn’t known Greg long, but he looks after her, and he loves playing dad to her young daughter. How could she say no when he’s already planned their elopement? As guests arrive, why is Greg acting so shifty? And is that a flicker of recognition on Zoe’s face? And why does she look terrified every time her phone rings?

My darling son, Sam, is marrying his childhood sweetheart, and I couldn’t be prouder of the man he’s grown into. Walking out on his abusive father all those years ago was the best thing I ever did. And today he stands, tall and handsome, saying "I do" to my dream daughter-in-law. If I hadn’t pushed them together all those years ago, he might never have found a girl as perfect as Lauren. It’s true what they say, mother always knows best. 

She bursts into my life like a storm, and nothing is the same again. One by one, I watch as my friends fall under her spell. Only I see that her smiles don’t reach her cold, furious eyes. And when I’m accused of things I didn’t do, when my home is vandalized, I know she’s behind it. But she only lets her mask slip when no one is looking, so if I say anything, I’ll look crazy. So when the baby shower comes around, I’m sitting on a velvet sofa in a posh hotel room, surrounded by balloons. But that afternoon, I finally learn the unbelievable truth. There is no baby....

When I met Malik my life changed in the blink of an eye. We were set up - Chris and Simon called it a blind date - and I suppose they could see that I was lonely, that I needed someone in my life to make it more exciting. And they were right. He was so good to me. He seemed to know exactly what I needed to feel safe and loved again. We’d talk and laugh into the night, and I haven’t had someone on my side since my divorce. But soon the honeymoon period was over. It started with my car’s tyre being slashed and strange calls at the radio station where I work.

Rachel is determined to be the perfect mother. She has a birth plan, with a playlist and a bag ready by the door. She’s chosen a lovely light cream paint for the nursery, and in wide-eyed, innocent Abbie she’s found the perfect person to help her with her baby. Because every mother needs a bit of help, don’t they? But Rachel needs a little more than most. She still makes sure her bedroom door is locked before she goes to sleep. She still checks the cameras that are dotted throughout the house.

Ever since Steph’s husband walked out after a 30-year marriage, home hasn’t felt like a safe haven. Her daughter Bea thinks she’s imagining things. But Steph knows that the noises in the night, the open windows she knows she left closed, the strange smell in the kitchen - none of it feels right.

From the outside the parents of the kindergarten class at Darley Heights primary school seem to have it all. Living in the wealthy Sydney suburbs, it's a community where everyone knows each other - and secrets don't stay secret for long. The big date in the calendar is the school's annual fundraising trivia night, but when the evening gets raucously out of hand, talk turns to partner-swapping. Initially scandalised, it's not long before a group of parents make a reckless one-night-only pact. But in the harsh light of day, those involved must face the fallout of their behaviour. 

After every parents' evening, friends Nina, Bel and Rachel look forward to their regular debrief at the pub. But there will be no clinking Prosecco tonight. They are discussing an anonymous note that has been left in a child's schoolbag: this class has secrets. All the parents tell lies. As more notes are discovered, scandalous accusations are made and the school playground becomes rife with rumours. Who could be revealing the three friends' secrets? Because they thought the only people who knew everything about them were each other....

Everyone’s invited. Someone will never leave. In a grand townhouse rented specially for the evening, Hannah beams at her guests under the sparkling chandelier. Her sisters, her mother and aunt, her best friends...although she’ll miss them all so much when she moves away, tonight is about celebrating the happy times and raising a toast to the future. But the next morning, one of the guests is found cold and lifeless in their pristine white bed. Hannah is desperate to call the police. After all, it must have been an accident.
