On a vacation cruise to Central America with his wife, 70-year-old ex-Marine Sten Stensen kills a gun-wielding robber menacing a busload of senior tourists, in this novel by the author of The Road to Wellville and Talk Talk. 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 after becoming involved with Sara Hovarty Jennings, a hardened member of the anarchist Sovereign Citizens' Movement. Although Stensen endeavors to connect with Adam, the increasingly paranoid young man kills twice, spurring a massive manhunt in the mountains.

"[This book] is a masterly—and arresting—piece of storytelling, arguably Mr. Boyle's most powerful, kinetic novel yet."—NYTimes
