With a page-turning plot and characters that leap off the page, this is the story of an obsessive friendship and dark secrets that can no longer be hidden.

'Truth or dare?' she asks.

I hesitate. I have so many secrets, so many things I don't want to reveal, but this is only a game, only a bit of fun. 'Truth,' I say finally. 'I can imagine one of your dares, and I don't fancy running down Oxford Street naked tonight.'

'Truth,' Alice says slowly, drawing out the vowel sound as if she's savouring the word. 'Are you sure? Are you sure you can be completely honest?'

'I think so. Try me.'

'Okay.' And then she looks at me curiously. 'So. Were you glad, deep down? Were you glad to be rid of her? Your perfect sister? Were you secretly glad when she was killed?'

Katherine has moved away from her shattered once-perfect family to start a new life in Sydney. There she keeps her head down until she is befriended by the charismatic Alice, and her life takes her in new directions. But there is a dark side to Alice, and as we learn the truth of Katherine's sister's death and Alice's background their story spirals to an explosive finale.

A potent, intense and simply unputdownable psychological thriller from an exciting voice.
