Seth Cavanaugh was an undercover cop trying to take down a very dangerous guy that no one could touch. While undercover Seth met Honor and from the moment he saw her he was drawn to her. Honor was in the beginning of her FBI career and she took a chance on Seth. She knew that he had a somewhat tarnished reputation and that he had so dirty associates but she thought that maybe he would change for her. They fell in love hard and fast, but when things in Seth's investigation started to pick up he chose to learn Honor in the dark about who and what he really did. He cut her out along with his family and started down a dark road that lasted years.
After years of hunting down missing children for the FBI and a near death experience Honor decides that she needs a change. That change comes in the form of Last Chance Rescue. Her first big operation is a possible string of missing girls from across the U.S. All of them are college students but that is all they really have in common at first glance. The main girl that is being investigated in this case is Kelly Cavanaugh, Seth's niece. Seth was the last one in his family to know that his niece had gone missing and when he can't find any leads on his own he knows he needs help. Last Chance Rescue was his best option but he never thought that he would see Honor there.
Seth and Honor must work together and figure out how and if these missing girls are connected and find Kelly before something terrible happens. I really liked both Honor and Seth they were great lead characters. The romance took awhile to develop and at times you just wanted to shake both characters and make them see sense. I really liked this book and it can be read as a stand alone in the series.
