Someone’s after a deadly weapon… and only she can stop them.

It’s undercover ATF agent Randee Jareau’s job to make sure the government’s 3D printed “ghost gun” doesn’t fall into the wrong hands. So when someone goes after scientist Ace Steele, she must protect him… before she loses the undetectable weapon and its creator.

But with a mole inside Ace’s company and everyone a suspect, this assignment could become Randee’s last.
