It started out as a party: six little girls gliding and giggling at the ice rink to celebrate Natalie’s daughter’s eighth birthday. But by Natalie’s next head count, it’s turned into a crime scene. Six children went onto the ice—and now there are just five. Nobody saw her niece, Elle, being taken. Nobody saw the person in a cartoon costume lure her quietly away. Traumatised by what happened on her watch, Natalie spends the next decade supporting her sister, Jo, as the years since Elle’s abduction tick by.

Mothers talk about impossible choices. But, as I look at my daughter in a hospital bed, her red hair fanning out around her, my heart feels literally torn in two. Should I risk my son’s life to save my daughter, or keep my little boy safe and watch my precious girl slip away? My darling daughter Tara has a rare form of cancer and there’s nothing I can do. At eleven years old, she’s already been so brave, but my sweet girl is hanging on by her fingernails. She has one last chance: a bone marrow transplant from her little brother.

When Megan loses her beloved husband, Rick, in a tragic car accident, she feels like it’s her own life that has ended. She feels too young to be a widow.

A heavily-pregnant young woman, with a sweet heart-shaped face that is somehow a little familiar. This stranger introduces herself as Emily, Rick’s estranged sister. She explains how she’s been searching for her brother for years, but she knows she’s too late now.

I’ve been married to my kind, loving husband Lachlan for over twenty years. He’s my everything. We have two teenage children, a beautiful home and I feel so lucky to live this perfect life. Until my best friend says something that makes me doubt everything… She whispers it’s strange Lachlan has lived nearby to two unsolved murder cases. First, the murder of the woman in the small, Scottish village where he grew up and more recently the shocking death of a woman who lived round the corner from us. The thought makes my head spin. It’s just a coincidence, surely?

You trust them with your child. You shouldn’t. Each Monday after school, I look after my daughter Coralie and four other kids from her class. We go to the park when it’s sunny, snuggle on the sofa reading books when it rains. Tuesdays to Fridays, the other parents take them. It’s perfect–a circle of free childcare, of fun and friendship for our children. But this morning, we all received an anonymous note. And now I’m terrified.

When Emily’s husband dies in a terrible accident, she’s not the only wife he leaves behind.

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.

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.
