Isabelle knows her friends are being murdered, but no one believes her.  All she can do is hope no one else gets hurt.  To make sure that happens, she pleads with them to be careful and calls on a friend and hero from her past. Grant saved her from being molested when she was in foster care and, above all else, she wants to keep him out of harm's way.

Grant is used to being in the way of danger.  Retired now from special forces, he is looking forward to working with his buddies on more peaceful ground.  When he gets the call from Isabelle, instead of blowing off her pleas to be careful, his instincts kick in.  He arrives on her doorstep to hear the tale that several of their foster siblings are dead by apparent suicide.  When someone tampers with Isabelle's car, the police and Grant believe it is a man who is angry that Isabelle is his son's foster mom.  More accidents happen, and soon Grant has his hands full doing all he can to keep the people he is beginning to love safe.

Excellent drama is employed in this book.  Emotions are on key and even though you know who the killer is almost from the beginning, you still can't be sure he will be caught.
