As his career path led him into more and more danger, Calum made a decision to keep his family safe, even if it meant he would be alone in the world. But when his wife and son are kidnapped and dumped almost into his very own secret headquarters, Calum knows his safeguards haven't been enough.

Mariana didn't like Calum's decision from years ago but finally understood after her and her son are rescued from kidnappers, and she saw the dangerous level of his work. However, having him once again in her life, their family whole again, she's not willing to let him go. Not this time. If the danger would continue, ... surely they were safer at his side.

Calum's abilities at an all-time low, his friends and fellow teammates injured and struggling, Calum knows he must be there for the team. Yet protecting his family comes first. But, if they don't get to the bottom of the chaos that's his current life, ... no one is safe.
