Coming home after seven years from Afghanistan, Jace Austin estranged himself from the people around him for having a secret that must be kept for as long as he is alive. He cannot put someone he cherishes in jeopardy, so he willingly accepted the fact that he will not be able to reconnect with his loved ones because he knew danger will follow him wherever he goes - because in underground, he is dangerous, has a bounty on his head, a killer with the codename "Five." As Five, he is a cunning, cold-blooded animal who will prioritize his mission above anything else even if it means abandoning everything he had brought - including his allies. But as Jace, he is everything Five isn't. Having to live both lives, how can Jace survive living after coming home? How could he keep his secret from everybody?
