Austen Payne, THIRDS Squadron Specialist Agent (SSA) for Destructive Delta and TIN operative, has seen the worst the world has to offer, faced lethal killers, and helped bring down dangerous organizations.

When Zach foils an assassination attempt, he ends up in the killer's crosshairs, and Austen is Zach's best chance at staying alive. Zach hopes the crisis will bring them closer, but Austen has every intention of walking away as soon as the danger is over. Happily ever after isn't for guys like Austen, but Zach is determined to show him it can be....
