I took my twin sister’s life. By life, I mean I replaced her. Is my new baby worth the price?

I’m Beth. Or I was, until the crash.

I’m a woman clinging to the frayed edges of a failing marriage. We’ve been trying for a baby for ten years now, and the strain of it all is destroying us.

My twin sister Cate has everything I’ve ever wanted — three perfect children, an adoring husband, a beautiful home.

The world revolves around her. I’m the paler, watered-down version.

Then comes the accident. A twisted wreck on the motorway. A single, devastating moment.

And a choice.

They thought I was my twin sister. And I didn’t correct them.

Now I’m living her life. Sleeping in her bed. Raising her child . . . But someone knows what I’ve done.
