Devil’s Breath Volcano In this sixth adventure of the MacGregor family, Chris MacGregor leads his brother, R.O.,his sister, Heather,and his girlfriend, Natalie, through the beautiful underwater world of the South Pacific and into the exotic rain-forests of New Guinea in search of a deadly chemical that is destroying the pristine pearl beds of the Bismarck Sea. Marine biologist Dr. Randy Heath calls his friend Jack MacGregor and informs him that he has found cyanide in the marine ecosystem around his pearl beds on Long Island off the coast of New Guinea. Teaming up with Billy Fly, who owns a local restaurant and resort, the MacGregors go in search of the source of the pollution. There, they encounter evil profiteers who will do anything to preserve the huge gold reserves they have discovered in the bowels of an active volcano. Fighting against time, the MacGregors are aided in their search by native islanders who wear the shrunken heads of their enemies. With a World War II air battle, a secret safe on a sunken Japanese destroyer, and an underwater shark encounter, Devil’s Breath Volcano introduces children to new cultures, teaches science and history, and stands as another exciting trademark adventure by author Richard Trout.
