In Grippando’s rousing ninth Jack Swyteck legal thriller (after Born to Run), Jack successfully defends a supposed Somali prisoner in his mid-20s held at Guantánamo. But then the prisoner is identified as an American, Jamal Wakefield, and is transferred to Miami, Fla., where he’s charged with the fatal stabbing of his ex-girlfriend, McKenna Mays, three years earlier. In his defense, Jamal offers a wild story of kidnapping and covert interrogation. As witnesses who could confirm Jamal’s alibi are eliminated, Jack and his dwindling circle of friends, and not always trustworthy allies, must race to uncover a sadistic killer and his bosses before the conspirators can silence everyone who might speak against them. Working with a cast that includes depraved sexual deviants, corrupt private military contractors, and wannabe jihadis, Grippando transforms what might have been a conventional genre novel in lesser hands into an exciting tale of revenge.
