Captain Chase Anderson is a distinguished war veteran, widow, and single mother in charge of Public Affairs at the base in Hawaii. After a Marine-81 helicopter-the very model her husband, Stone, was flying when he crashed in Afghanistan-goes down five miles off the coast of Oahu, Chase begins to suspect a conspiracy to minimize, even hide, the defects within the Marine-81. Despite threats to her career, Chase follows her hunch, and the search for the truth, a search that implicates everyone from Hawaii to the Pentagon, eventually leads her back to the disturbing truth about Stone and their marriage.
