When Kate Kingsbury and crew rush to help after a brutal hurricane widows a family friend, they stumble on an ancient mystery. Five indigenous idols are scattered throughout the Caribbean. Together, they hold the key to a fortune - and murder. Hunting the idols thrusts Kate, Whiskey, and the Shark Key family into a race against time from the Dominican Republic to the Everglades. Because, unknown to Kate, a false shaman also seeks the idols. With each idol he finds, he kills. So Kate and her friends must collect the remaining idols before another teen is slaughtered.
