t’s been five years since Special Agents Ty Grady and Zane Garrett first worked together to solve the Tri-State murders, and time has been both harsh and kind. Engaged now, they face the challenge of planning a deeply uncertain future together. Zane is at the pinnacle of his career with one last mystery to solve, while Ty is at sea in a world where he’s no longer the tip of a spear.

There’s just one more hurdle in the way of their happy ever after: a traitor from their inner circle who threatens to burn their world to the ground.

Squeezed between the Vega cartel, an unknown mole, and too many alphabet agencies to count, Ty and Zane must gather all their strength and resources to beat the longest odds they’ve ever faced. To make it out alive, they’ll need help from every friend they’ve got. Even the friends who might betray their trust.
