The brand-new psychological thriller from Claire Allan, perfect for fans of K L Slater and Claire Douglas. Two years ago, I tore her world apart.

Now, I’m going to make her my best friend. Every day for the last year, I have lived the same small existence, barely leaving my flat, willing for something to change.

And it finally is. I'm taking control of my life, and the first step is meeting Sorcha Hannon.

Perfect, beautiful Sorcha, who has managed to lift herself out of the darkest of times. After a devastating broken marriage, she's found the healing and hope I desperately want to find for myself.

With Sorcha’s friendship, I am no longer alone. Instead of days working from home at my mundane job, I’ll have someone to talk to.

I’ll find the courage to take up wild-water swimming – driving to the coast with Sorcha and her friends, holding hands as we walk into the Atlantic. I will feel as if I finally belong.

There’s just one small catch. Sorcha Hannon isn’t just a new friend to me, and she certainly isn’t a stranger.

In fact, I know the ins and outs of her life, and her marriage, almost as well as she does. But if she finds out who I really am, I’ll lose everything.

Then again as Sorcha says, no one’s life is really as perfect as it seems… and I should have realised, I’m not the only person with secrets. .
