Hailey Cain has a history of testing the limits of her fate: as a fearless bike messenger on the streets of San Francisco; as a young female cadet at West Point. When an old friend from her former life in Los Angeles calls in a favor, Hailey doesn't have to think long before she accepts the mission. From the dustiest Mexican roads to the meanest streets of East L.A., Hailey finds herself ensnared in a war more deviant and ugly than any she trained for as a cadet. Deep in the gang underworld, pusued by mobsters and authorities alike, Hailey must use her instincts to stay alive--and to protect the innocent from a past that still haunts her.
