When Emily lets a stranger step out in front of her, she never imagines that split second will change her life. But after Emily watches a car plough into the young mother – killing her instantly – she finds herself unable to move on.

And then she makes a decision she can never take back.

Because Rose had everything Emily had ever dreamed of. A beautiful, loving family, a great job and a stunning home. And now Rose’s husband misses his wife, and their son needs a mother. Why couldn’t Emily fill that space?

But as Emily is about to discover, no one’s life is perfect … and not everything is as it seems.

It’s six in the morning during the hottest summer on record when Elizabeth O’Loughlin, out walking her dog, comes across Clare, a victim of a horrific knife attack, clinging onto life at the side of the road.
 
Clare dies minutes later, but not before whispering her haunting last words to Elizabeth.
  
When it becomes clear that Clare’s killer has more than one murder on his mind, Elizabeth has to take drastic action or face losing everything.
 
But what if she can’t stop a killer determined never to be forgotten?
