War Hawk

Former Army Ranger Tucker Wayne and his military dog, Kane, are thrust into a global conspiracy in this second Sigma Force spinoff adventure from New York Times bestselling authors James Rollins and Grant Blackwood
Tucker Wayne’s past and present collide when a former army colleague comes to him for help. She’s on the run from brutal assassins hunting her and her son. To keep them safe, Tucker must discover who killed a brilliant young idealist—a crime that leads back to the most powerful figures in the U.S. government.
From the haunted swamplands of the deep South to the beachheads of a savage civil war in Trinidad, Tucker and his beloved war dog, Kane, must work together to discover the truth behind a mystery that dates back to World War II, involving the genius of a young code-breaker, Alan Turing . . . 
They will be forced to break the law, expose national secrets, and risk everything to stop a madman determined to control the future of modern warfare for his own diabolical ends. But can Tucker and Kane withstand a force so indomitable that it threatens our future?

“[A]nother outstanding adventure. Fans of Tom Clancy, Brad Thor, or Rollins’ previous titles will enjoy this, and hopefully Wayne and Kane will appear again, perhaps in the next Sigma Force title.” — Booklist on WAR HAWK
“Kane, a Belgian Malinois, is the standout character, more than just a plot device and never anthropomorphized. His point-of-view chapters reveal his loyalty, fear, intelligence, and even a desire for revenge. Kane’s a good boy!” — Publishers Weekly on WAR HAWK
