The phone rings. What Eva doesn’t realize is that the call will signal the end of what she knows to be true. The end of trusting her family. And the end of everything keeping her safe. The phone call is from a hospital hundreds of miles away. A woman has been admitted with a serious head injury, saying she’s Eva’s older sister. A sister Eva never knew she had. Whose name - Nancy - has never once been mentioned by her parents. It seems impossible. Could the two people who brought Eva up have lied to her for her whole life?

Carly had thought they’d always live there. The beautiful Cornish cliffside house they’d taken on as a wreck, that Mark had obsessively redesigned and renovated - a project that had made him famous. It was where they’d raised their children, where they’d sat cozily on the sofa, watching storms raging over the sea below. It was where they’d promised to keep each other’s secrets. Until now. Because Mark has fallen in love. With someone he definitely shouldn’t have. Someone who isn’t Carly. And suddenly their family home doesn’t feel like so much of a safe haven. 

All the neighbours were laughing, drinking out of plastic glasses and getting along. I almost felt happy. Almost forgot about the terrible argument earlier and the sinister messages I’d been receiving from a strange address all week, threatening to expose the lies behind my perfect life. As we finished with the red and gold fireworks and welcomed everyone back to our house, I believed that everything would be okay. But I didn’t know who I was inviting in.

I thought my sister was happy. I thought what we all thought: that Annie and Dom led perfect lives in a lovely cottage in a quiet village by the sea, with flowers at the front gate and an apple tree in the garden. Everyone knew them: generous, loving Dom, creative, joyful Annie. But I never saw Annie as she sat waiting for Dom well into the night. I didn’t see her smiling through her tears. I didn’t know what the perfect couple was hiding.

Paige, Richard and me. We thought we’d be friends forever. But everything changed the day we took the shortcut home from school along the old railway line. I wish we’d gone the long way. I wish we hadn’t seen our classmate, pale and still in the undergrowth. And I wish we hadn’t promised to keep one, awful detail a secret just between us....

In a patch of forest on the outskirts of a small town, five teenage school friends prepare to spend a night away from home. Carrying their tents and sleeping bags, they laugh and joke as they make their way into the darkest part of the woods, away from prying eyes. But as the sun rises the following morning, only four are left alive. 

I wrap my arms around the tree trunk, pressing my cheek against it until the bark digs in and the missing poster is finally secured. I try not to look at the photograph on it. At the features so similar to mine. Perhaps this will be the year someone comes forward. Were crucial mistakes made by detectives from the very beginning? Could the pressure of living two lives have led my sister to run away - or even end it? Or did someone in her tight circle of friends and family have reason to want her gone? Someone out there must know something.

I know I have to stop pretending that nothing is happening. I can’t escape the truth. Someone knows my secret. But what do they want from me?
