Spoiler:

Richard Mariner of the Heritage Mariner shipping company has commissioned two identical ships designed to transport nuclear waste safely across the Atlantic.

Within months of surviving a terrorist attack at their launch, the sister ships are in service, but suspiciously bad luck and foul weather trap the Atropos behind a huge ice barrier.

Crippled and helpless, she is in imminent danger of being crushed.

Clotho, the only ship close enough to help, plunges into the stormy Labrador Sea, her crew totally unaware that the bomb has done more damage than anyone suspects.

And that was but the opening move in a campaign of violence by a death-defying group of environmental terrorists who are already aboard, disguised as members of the crew and secretly stowed away.

One lethal device has already been planted and more have been smuggled deep into the bowels of the great ship ...

It is up to Richard and Robin Mariner to save themselves, their crew and their company.

But in deep waters, no one is safe ...
