'A master of sea-going adventure. Enough taut suspense to satisfy any reader.' Clive Cussler

When a large rogue wave forms in the North Atlantic, three unsuspecting vessels are forced to protect themselves as best they can from the onslaught.

Among these ships is Richard Mariner's trusty tug Sisyphus which, due to his quick-thinking and bold risk-taking, is saved from the worst of the wave's effects.

However, when Richard's wife, Robin, is swept away by the wave he soon realises that his troubles have only just begun.

As the other two boats fail to fare as well as the Sisyphus, with one lost and the other badly damaged, Richard aids the battered Quebec submarine up to the surface of the water, so that Canadian Fleet Command can take over.

But as those aboard the Quebec face threats from both the merciless sea and those within their midst, Richard and his crew must rapidly adapt to an ever-worsening situation.

Richard Mariner must face one of his most difficult challenges yet: balancing loyalty to his wife and professionalism in his work. Mariner could lose everything.
