When the US Navy's new, state-of-the-art missile disappears after its test launch, panic ensues - if it ends up anywhere near civilians, the consequences could be massive. Where has it gone? What has happened?

Seemingly unconnected, journalist Carol Dawson is investigating the unusual sightings of whales in Miami, which may or may not be linked to the missing rocket. Armed with Oceanographic research equipment, Carol charters a boat skippered by Nick Williams and Jefferson Troy and heads to the Gulf of Mexico.

What they find can barely be explained but could be worth untold riches.

While Carol, Nick and Jefferson attempt to uncover the origin of the mysterious artefact they have discovered, they must dodge treasure hunters, the government, and consider the origin of humanity itself. Is this the First Contact? Or is it the last?
