This fierce K-9 is facing killer odds.

Security agent Granger Morais is stunned when he and his K-9, Zeus, confront the one person he thought was dead — and can’t afford to trust again.

But when Granger must protect her from a ruthless cartel that wants her special skills, will his and Charlie’s troubled history — and reignited heat — keep them alive...or be the one trap they never saw coming?
