"I have no idea what I'm supposed to do with you."Since Grayson Pierce's family was murdered, loyalty to Code X—and a death wish—is all that keeps him going. But now the hardened agent is facing his riskiest assignment yet.

It will take all of Grayson's training to stay focused as he and Sam uncover a dangerous high-tech conspiracy. Because he can't risk the consequences to national security…or the woman who's jump-started his will to live.
