Two things threaten to destroy several areas of Daron Kincaid's life--the tracking device he developed to locate victims of sex trafficking and an inherited membership in a mysterious outfit called The Castle. The new developments set the stage to dismantle the relationship with Cameron, the woman he loves, as well as the new life he's building outside of an FBI sting that brought down his former enemies. Coming out of the shadows could have dangerous consequences that affect everyone around him. Marquise Sinclair, a crime boss over an international theft ring, is determined to take Daron's position in the Castle by leveraging Cameron's life against a project worth billions. Unfortunately, he is unaware that his lovely target was fiercely trained to make men weak or put them on the wrong side of the grave. The secrets Daron keeps from Cameron and his inner circle only complicates an already tumultuous situation that isn't of his own making. Can Daron take on Marquise, manage his secrets and loyalty to the Castle without permanently losing the woman he loves?
