Her name was Rose. You watched her die—and her death has created a vacancy.

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

Then she makes a decision she can never take back.

Rose had everything Emily had ever dreamed of: a beautiful, loving family, a great job, and a stunning home. Now, Rose’s husband is left grieving his wife, and their son is in need of 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.
