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.
