Robert McCaw Books in Order

Hawaiian detective Koa Kane investigates a mutilated body discovered at an army training area, its injuries suggesting ritual sacrifice. Conflicting accounts and local tensions obstruct his search for a killer whose motive may involve stolen antiquities or a dangerous secret.

Two gruesome deaths draw Koa Kane toward a reclusive couple concealing fugitive identities. As intelligence agencies and political pressures obstruct the investigation, he follows the linked murders into an international conspiracy reaching far beyond Hawaii.

An elementary school’s catastrophic location over a volcanic vent sparks Koa’s investigation, intensified by murders of its architect and contractor. A crisis involving his imprisoned brother complicates the case, threatening to put family loyalty in conflict with justice.

A murder weapon implicates Koa Kane’s brother just as a sniper attacks his closest colleague. Searching for connections between the crimes, Koa begins to suspect that someone is using the people around him to exact revenge upon him.

An earthquake exposes a concealed murder victim, leading Koa toward a powerful defence contractor and an espionage case. Meanwhile, scrutiny of his own long-hidden crime threatens to implicate an innocent man, confronting him with the cost of continued silence.
