Sinister international forces plot to destroy a natural barrier reef in order to stake a claim to gold doubloons and Colombian emeralds hidden for nearly four hundred years.

Amid the exotic waters and beaches of the Cayman Islands, this tale conveys an exciting mix of pirates, strange and timeless creatures of the sea, and the hospitable peoples of the Caribbean. Fast boats, mini-subs, undersea scooters, hurricanes, and even teen romance accentuate the fast tempo of this techno-thriller, the first in a series.

The MacGregor family's respect for life and the sanctity of the environment, along with their thirst for adventure, drive the teens through a series of challenging and surprising events. Along with page-turning excitement, Cayman Gold delivers gentle doses of history and geography along the way.
