Concepcion Chapa, an Army veteran, FBI special agent, and the orphaned daughter of two CIA agents, has lived a life of sacrifice for her country. When she learns that her parents may not be dead, just undercover, she allows herself to be recruited as a killer-for-hire for the CIA. Faking her death and undergoing surgery to change her looks, Concepcion leaves everything behind-her friends, family, and country. Under the identity of Sofia Paltrini, she travels the globe doing the dirty work of the US government. But in a world of subterfuge and hidden motives, no one is quite who they seem. Concepcion is left not knowing who to trust and wondering if there's a way to live a life for herself that's beyond sacrifice.
