In Vector, Rob Swigart introduced Detective Cobb Nakamura of the Kauai police and microbiologist Chazz Koenig in a potent thriller mixing myth, science and murder. Toxin returns to the tiny Hawaiian island with a gripping novel of a local shooting and international intrigue. The quiet beauty of Kauai is disturbed when a wealthy developer is murdered. Then a satellite carrying an unknown toxin falls onto the island, poisoning several people and causing a panic. Only Chazz Koenig's expertise in cell biology and Takamura's careful sleuthing can piece together the entire picture and restore peace to the island.
