Secret military weapons, saboteurs, a volcanic eruption—and a probe of Chief Detective Koa Kāne's criminal past

On Hawaii Island, a volcanic earthquake disrupts an abandoned cemetery—unearthing the body of a woman mutilated by her killer to conceal her identity.
The search for her identity leads Hilo Hawaii's Chief Detective Koa Kāne to a mysterious defense contractor with a politically connected board of directors. Defying his chief of police, Koa pursues the killer, only to become entangled in an FBI espionage investigation of Deimos, a powerful secret military weapon. Is the FBI telling all it knows—or does it, too, have a duplicitous agenda?
