Years agos, Lucas Davenport almost died at the hands of Clara Rinker, a pleasant, soft-spoken, low-key Southerner, and the best hit-woman in the business. Now retired and living in Mexico, she nearly dies herself when a sniper kills her boyfriend, the son of a local druglord. While the boy's father vows vengance, Rinker knows something he doesn't ... the boy wasn't the target--she was--and now she's going to have to have to disappear to find the killer herself.
