Tall and handsome, twenty-six-year-old Alexander Karastinos is passionate about life and living it. Popular with his friends in the small Greek community of Tarpon Springs, Florida, he works hard in the dangerous profession of sponge-fishing. Alexander enjoys spending his free time with his gorgeous and exotic Cuban girlfriend, Silvia Morales. But his comfortable life and his relationship with Silvia are suddenly turned upside down by his father's surprise announcement at a family dinner. Quietly, the patriarchs of the Karastinos and Demetrias families have arranged a marriage between Alexander and Melena Demetrias. Neither of them believes they are ready for marriage, but Alexander and Melena understand the consequences of refusing their parents' wishes. In the days and months that follow, Alexander and his older brother Taso come to grips with their personal challenges while crossing paths with a dangerous man whose legacy for hating all Greeks places young Alexander in grave danger. Only a mysterious old Greek woman in black stands between Alexander and the evil she knows he faces.

Twelve-year-old Jasmine Lopez loves exploring the coral reefs around Fiji where her marine biologist parents are stationed, and though young, she is already a certified scuba diver, a fact that her ten-year-old brother Arjun seems to resent; in fact he seems to believe he already knows everything about diving, and certainly does not want help from his older sister--until his overconfidence and defiance leads them both into a confrontation with a reef shark.
