Claire and Eva lead very different lives, but they have one thing in common - they are both in huge danger and need to disappear. A chance encounter at the airport presents the two women with a simple but crazy solution: switch places and then drop off the grid when they land. But one woman will never reach her destination. 

Since Alice’s fiancé walked out on her, she never thought she’d meet "The One". But all that changes when she meets Dominic. Handsome, charming, and kind, Alice can’t believe her luck when he proposes a few months later and moves into her West London home. Three years on, Alice’s catering business is thriving and she is married to a man she adores. So when she sees that little blue line, it should be the happiest moment of her life: they’re going to have a baby. But then the police knock on her door and Alice’s whole world is turned upside down...Dominic is dead.

Beth and Cath are leaving their husbands. This is a story about two very different women. One is wealthy and having an affair with a man who gives her the kind of love that her cold, detached husband does not. One is living hand to mouth, suffering at the hands of a violent partner who would rather see her dead than leave him. You may think you know these women already and how their lives will unfold. Beth will live happily ever after with her little girl and her soulmate. Cath will go back to her abusive husband. And these two women will never cross paths. But you will be wrong.

She was supposed to be a mother, but it hasn't worked out like she expected.

A woman screams in pain. Twenty-seven times, until she dies. The sound file was sent to DCI Mark Lapslie from an anonymous email address. Why is she screaming? Why would someone record that horrifying noise? And why send it to him? He soon learns that the file was sent from the hospital where he is being treated for synaesthesia - a neurological condition that cross-wires his senses so he tastes sound - and where his new girlfriend works.
