Shelter in place. Nora Roberts. 2018.

When the shots rang out in the shopping mall, Simone Knox knew what to do. Shelter in place. So on that terrible day, when so many died, she was lucky. She survived.

More than ten years later, and now an acclaimed artist, Simone still struggles with grief and misplaced guilt. Living on a peaceful island off the coast of Maine, she begins to open up to Detective Reed Quartermaine - another survivor of the shooting. Perhaps she can transform herself, and put the past behind her?

But someone has been watching al the survivors of the DownEast Mall massacre, perfecting a plan to finish what was started. Now Reed and Simone are in more danger than ever - from a killer who will not, and cannot stop.
