‘Your life is perfect,’ Anna says, smiling across my dining table. But something in her tone and the glint in her hazel eyes lets me know the comment is laced with jealousy. I sip my wine and smile. Soon she’ll learn that having this life costs more than she could ever imagine...

Everyone thinks I’m living the perfect life. I have my dream job, a stunning apartment, and glamourous friends – who know nothing about my dark past. So I’m shocked when I run into Anna, who I haven’t seen in eighteen years. Everything about her reminds me of the life I’ve left behind. But as her eyes fill with tears and she tells me she’s lost her job and can’t pay her rent, I reluctantly offer her my spare room.

Anna promises she won’t stay for long. But soon, I notice she’s wearing my designer clothes and has dyed her hair to match my exact shade of chocolate brown. As I watch her curled up on my sofa, my blood runs cold. Did Anna really come back into my life by chance? What is she hiding?

Then I receive a chilling anonymous phone call telling me my time is up. Memories of that terrible night that changed everything come flooding back. The flames. The thick smoke. Someone knows what I did, and they want revenge.

But whoever that someone is, they’ve underestimated how far I’ll go to protect my perfect life…

For fans of Lisa Jewell, Gone Girl and The Housemaid, this is a completely gripping psychological thriller with a jaw-dropping twist.
