I feel the steady thump of my new heart beating inside me. The surgeon said everything went well. But I can't stop thinking about my donor: the girl who was killed. Her death saved my life. But now whoever took hers is coming for mine...

I can't believe it when I learn my donor's identity. The attack on Flora was all over the news. From my hospital bed I read every article, obsess over every word and soon I feel like I know her: the beautiful girl with flame-coloured hair, adored by everyone around her. Why would anyone hurt someone so perfect?

When Flora's family reach out to me, I'm unsure. My hands are shaking as I arrive at their grand mansion with its golden stone and sprawling gardens, but they're warm and welcoming, tears shining in her mother's eyes as she smiles at me.

She even tells me to take anything I want from Flora's things, as she can't bear to go through them herself. I run my fingers over the racks of beautiful designer items, carefully choosing outfits in Flora's signature yellow, the bright colour complementing the new flush in my cheeks. I think of the years I've wasted being ill, and the crushing loneliness I thought would never end. I deserve this.

But then there's a violent attack on another patient who received one of Flora's organs. My heart - Flora's heart - races dangerously fast. Is it a coincidence?

Maybe I've made a mistake by stepping into Flora's life. Has this second chance really saved me? Or has it cost me everything?

A totally gripping psychological thriller that will keep you turning the pages late into the night. If you loved The Silent Patient, The Housemaid and The Doctor's Wife, you won't want to miss this.
