Secret military weapons, saboteurs, a volcanic eruption --- and a probe of Chief Detective Koa Kane’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 Kane 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?

At the same time, Koa --- a cop who 30 years earlier killed his father’s nemesis and covered up the murder --- faces exposure by the dead man’s grandson. Koa is forced to investigate his own homicide, and step by step his cover-up unravels until another man is falsely accused.

Can Koa stand by and let an innocent man pay for his crime?
