THIRDS Team Leader Sebastian Hobbs and Chief Medical Examiner Hudson Colbourn are as much in love now as they were nearly seven years ago when a tragic event on the job destroyed their relationship. The two drift together only to be pulled apart time and time again. When Hudson draws the interest of dangerous enemies, both within and outside the organization, Seb wants nothing more than to protect the man who still means everything to him.

As life and death events, an uncertain future, and startling truths draw Hudson and Seb to each other yet again, they must make a choice: trust their love and take strength from what they share, or lose what matters most for good this time.
