Anthropology professors Laly Lawrence and Sugar Stephens are modern, independent women. They're also certified deep sea divers--and they're in the middle of the Caribbean searching for ancient artifacts. Then, after an unexpected earthquake and a storm, Laly braves the aftershocks and dives down for one last look...and finds hidden treasure. Sugar plunges in after her--and suddenly, both women are swept into--of all things--a time slip!
They surface--only to be caught in the middle of a spirited battle between an English warship and a Spanish galleon. Laly and Sugar figure they're watching some sort of historical reenactment, but to Captain Devon Bradley and his smitten First Officer, the lovely creatures are all too real--and clearly meant for them.
