For Lev Prakenskii, the last thing he remembers is being lost in the swirling currents of the ocean and sucked deeper into the nothingness of a freezing black eddy off the coastal town of Sea Haven. Just as quickly, just as miraculously, he was saved - pulled ashore by a beautiful stranger - but Lev has no memory of who he was - or why he seems to possess the violent instincts of a trained killer. All he knows is that he fears for his life, and the life of his unexpected saviour.

Her name is Rikki, a sea-urchin diver in the small town of Sea Haven. She always felt an affinity for the ocean and the seductive pull of the tides - and now, for the enigmatic man she rescued. But soon they will be bound by something even stronger - each other's tantalising secrets that will engulf them both in a whirlpool of dizzying passion and inescapable danger.
