In the scorching heat of the Texas desert, Byron Tibor walks a fine line between hunter and hunted.

A former CIA operative with enhanced abilities, Byron's attempt to disappear leads him straight into the clutches of a town where nothing is as it seems. Kelsen County, a place of wealth and power, hides dark secrets behind its pristine facade.

As Byron navigates a corrupt legal system and uncovers the town's sinister underbelly, he finds an unlikely ally in Thea Martinez, a passionate defense attorney with her own agenda.

Together, they must unravel the conspiracy at the heart of Kelsen County before it's too late. With pulse-pounding action, complex characters, and twists at every turn, this thriller explores the lengths one man will go to reclaim his freedom and expose the truth—no matter the cost.
