Summary: Molly Burke is a death investigator and trauma nurse for the city of St. Louis who has seen every type of atrocity and more than her share of heartbreak. And she knows that no good deed goes unpunished. For years she tried to save the abused children who came through her ER. She's learned that she can save some kids, but others will be lost to their horrific families. Now, a child she once tried to save is all grown up. His life was unspeakable. His deeds are now unfathomable. And he wants Molly's attention. A killer has been created and he will stop at nothing to make sure Molly Burke won't ignore him now. To make matters even more complicated, Molly's brother asks her to watch his sixteen-year-old son, who seems to have left a string of "incidents" in his wake, forcing her to face the fact that no family is without its secrets. - "Goodreads"
