It is past 10 o’clock on a cold Friday night when Rebecca and her husband Jack’s doorbell rings. Outside is a woman who introduces herself as Jack’s ex-girlfriend, Cara. And she’s holding the hand of a shivering, blue-eyed, four-year-old girl who she claims is Jack’s daughter. Rebecca is shocked to discover he has a child from his last relationship - even one he hadn’t known about. Because becoming parents isn’t part of their life plan.

Ever since Ruby was tiny, she has been unique. Her smiles are magically rare, and she likes things done in a very particular way - her blocks are always color-coded, and her toy animals stand in regimented lines. She’s also the daughter of Sara’s dreams - even on days when being a mother to a three-year-old is exhausting. Not everyone understands Ruby like Sara does though. Not Sara’s husband Mike, and certainly not her disapproving mother-in-law, Barbara. So when circumstances force their family to move in with Barbara, Sara knows it’s going to make motherhood even harder. 

When Shelley first met Greg, her life had been full of possibility. A whirlwind romance, a dream wedding, moving into their first house together, thinking about starting a family.... But now, it’s 10 years since their wedding. Greg has gone. And there’s a room in the house where Shelley has shut a baby blanket away. She’s been managing to hide from her past. Until one day, everything changes. She sees the couple moving in next door, giggling as they walk up the path to their new home. The woman is pregnant. It’s like she has everything that Shelley has lost.

"I would do anything for you to get well again, baby girl." It’s a promise. Even though I know it means asking her father for help, going back there, risking everything. Whatever the cost, there’s no hesitation in my mind. Because that’s what you do when you’re a mother. You put your child’s life before your own. 

Maggie is a mother to a stroppy teenager, a wife to a befuddled husband and a daughter to two very different women. She has always known she’s adopted, but has she ever understood what that means? Not really. Following the death of her mother, Maggie finally feels able to go in search of her birth mother Morag, and heads to the Highlands of Scotland with her disgruntled daughter, Roxie, in tow, leaving her crumbling marriage to worry about another day. The family reunion is bittersweet, but everything is blown wide open when Roxie unearths Morag’s explosive teenage diaries.

When Catriona loses her baby girl at birth, it shatters her. But like a light in the darkness, Catriona is given the chance to adopt beautiful baby April, and now she cannot imagine life without her. The family's picture-perfect home is filled every day with April's warm giggles and joyful games. But when her daughter is just eight years old, Catriona gets the call that she has been silently dreading. April's birth mother, Lauren, would like to meet her.

I haven’t lived here long. The house is small and a little run-down, but each piece of faded floral wallpaper I peel away feels like unwrapping the second chance I never thought I’d get. I’m finally free to wear what I want, and I don’t flinch when I accidently burn dinner. My new home is warm, and the kids are safe inside. Anywhere would feel idyllic after the nightmare marriage I’ve just escaped.

When Emily’s husband dies in a terrible accident, she’s not the only wife he leaves behind. Before their whirlwind romance and Emily’s discovery she was pregnant, Pete had been married to Caroline for more than 20 years. A devastating tragedy had torn them apart. But there was a part of Pete that had never fully left his first wife and a secret that would bind them together, forever. Finding herself lonely, heartbroken, and forced to face life and motherhood alone, Emily knows she needs someone she can trust and rely on. Even if it’s the woman her husband loved before her. 

 Jenny has too much on her plate, literally - she’s pregnant with only one child, but she’s already eating for three. Not to mention trying to juggle her future life with a baby, a nightmare boss, a know-it-all sister, and a bizarrely laid back husband. 

Will I have the chance to explain to little Erin why I had to go? Even if I do find the strength to return, what will my mother have told her? Only one person really knows what happened and why I had to do what I did. I know the truth will come out some day. I don’t expect forgiveness. The only thing I hope is that my family can survive the fallout....

Single mum Rory doesn’t believe in love. She’s got far too many real problems to deal with. She’s just bought a tumbledown house. Her mother is generally behaving like a wicked witch, insisting on calling her Aurora and generally interfering in her (admittedly pitiful lack of) love life. And her 16-year-old daughter has finally grown out of Disney princesses and discovered dating....

When I was a kid and I’d lost something, my dad always said, ‘Go back to the place you last had it’. The problem is that what I’ve lost is...me. Kate loves her family more than anything, but recently she has started to feel invisible. Lying awake at three a.m. as her husband snores, panicking about shopping lists, birthday parties and the school bake sale...She finds herself in the kitchen, gulping water, staring at a postcard of the Eiffel Tower from Shannon, her best friend.  

In one split second, Aidan Whelan’s perfect world is changed forever when his wife, Rowan, and three-year-old daughter Milly are involved in tragic accident. Helena O’Herlihy and her husband, James, have been struggling in their marriage, but a knock on the door telling her that James has been involved in a car crash has Helena rushing to his side. When Aidan and Helena bump into each other at Dublin City Hospital, they soon begin to wonder if it’s more than just coincidence that brought them there.

When I found out I was pregnant, I couldn’t have been happier. Ever since my own father died, I’d felt utterly lost. But you changed everything. Finally, I had found my purpose: to be the best mother I could be. But I couldn’t–wouldn’t–tell anyone who your father was. I could never forget the look in his eyes that day. The betrayal written across his face. All the things we didn’t say and the secret that tore us apart.

When I first met you, darling Marina, you were just five years old. You took my breath away, with your long, dark waves and pink cheeks. You needed me, and I instantly knew I’d do anything to protect you. When six years ago, my heart was shattered, I was left utterly broken – but I didn’t know just how lost I was until you filled that hole in my heart. You quickly became the centre of my world, your sweet laugh my favourite sound. But then things started to change... I put my pain down to work stress, but when the diagnosis came through it was worse than I could ever have imagined.
