Tucker Wayne's past and his present collide when former army colleague Jane Sabatello comes to him for help. She's on the run from brutal assassins hunting her and her son. To keep them safe, Tucker must determine who killed a mutual friend, a brilliant young idealist--a crime that Tucker discovers 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 uncover the truth behind a mystery that traces back to World War II, involving the genius of a young code-breaker named Alan Turing. The threat of this enigmatic and dangerous secret has repercussions that could change our world forever . . . and redefine what it means to be human. With no one to trust, Tucker and his exceptional loyal companion Kane will be forced to break the law, expose national secrets, and risk their own lives 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 jeopardizes our very future?
