In the fall of 1863, the Union army is in control of the Mississippi river. Much of Louisiana, including New Orleans and Baton Rouge, is occupied. The Confederate army is in disarray, corrupt structures are falling apart, and enslaved men and women are beginning to glimpse freedom. When Hannah Laveau, a formerly enslaved woman working on the Lufkin plantation, is accused of murder, she goes on the run with Florence Milton, an abolitionist schoolteacher, dodging the local constable and the slavecatchers that prowl the bayous.

Against the backdrop of growing civil rights turmoil in a sultry border town, the hard-drinking ex-POW attorney Hackberry Holland yields to the myriad urgings of his wife, his brother, and his so-called friends to make a bid for a congressional seat - and finds himself embroiled in the seamy world of Texas powerbrokers.

Texas attorney and former Texas Ranger Billy Bob Holland has many secrets. Among them is Vernon Smother's son, Lucas, a now-teenaged boy about whom few know the truth - Lucas is really Billy Bob's illegitimate son. When Lucas is arrested for murder, Billy Bob must confront the past and serve as the boy's criminal attorney. Billy Bob knows the propensity of the town, Deaf Smith, Texas, to make scapegoats out of the innocent and to exploit and sexually use the powerless.

Haller is a Lincoln Lawyer, a criminal defense pro who operates out of the backseat of his Lincoln Town Car, to defend clients at the bottom of the legal food chain. It's no wonder that he is despised by cops, prosecutors, and even some of his own clients. But an investigator is murdered for getting too close to the truth and Haller quickly discovers that his search for innocence has taken him face to face with a kind of evil as pure as a flame.

The "maddog" murderer who is terrorizing the Twin Cities is two things: insane and extremely intelligent. He kills for the pleasure of it and thoroughly enjoys placing elaborate obstacles to keep police befuddled. Each clever move he makes is another point of pride. But when the brilliant Lieutenant Lucas Davenport, a dedicated cop and a serial killer's worst nightmare, is brought in to take up the investigation, the maddog suddenly has an adversary worthy of his genius.
