Unseen, pits detectives, lovers, and enemies against one another in an unforgettable standoff between righteous courage and deepest evil. Bill Black is a scary guy: a tall ex-con who rides to work on a Harley and trails an air of violence wherever he goes. In Macon, Georgia, Bill has caught the eye of a wiry little drug dealer and his cunning girlfriend. They think Bill might be a useful ally. They don't know that Bill is actually a Georgia Bureau of Investigation agent named Will Trent. Or that he is fighting his own demons, undercover and cut off from the support of Sara Linton--the woman he loves, who cannot be told of the risk Will is taking. Sara herself has come to Macon because of a cop shooting: Her stepson, Jared, has been gunned down in his own home. Sara holds Lena, Jared's wife, responsible: Lena, a detective, has been a magnet for trouble all her life, and Jared's death is not the first time someone Sara loved got caught in the crossfire. Furious, Sara finds herself involved in the same case that Will is working without even knowing it, and soon danger is swirling around both of them.
