The harder they come : a novel / T. Coraghessan Boyle.

On a vacation cruise to Central America with his wife, seventy-year-old former Marine and Vietnam veteran Sten Stensen unflinchingly kills a gun-wielding robber menacing a busload of senior tourists. The reluctant hero is relieved to return home to Fort Bragg, California, after the ordeal - only to find that his delusional son, Adam, has spiraled out of control. Adam has become involved with Sara Hovarty Jennings, a hardened member of the Sovereign Citizens' Movement, right-wing anarchists who refuse to acknowledge the laws and regulations of the state, considering them to be false and non-applicable. Adam's senior by some fifteen years, Sara becomes his protector and inamorata. As Adam's mental state fractures, he becomes increasingly schizophrenic - a breakdown that leads him to shoot two people in separate incindents. On the run, he takes to the woods, spurring the biggest manhunt in California history. As he explores a father's legacy of violence and his powerlessness in relating to his equally violent son, T.C. Boyle offers unparalleled psychological insights into the American psyche.
