Water Bound — Christine Feehan

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

Her name is Rikki, a sea~urchin diver in Sea Haven. She has always felt an affinity for the ocean, and for the seductive pull of the tides. And now she feels drawn in the same way to the enigmatic man she rescued. But soon they will be bound by something even stronger, and their tantalizing secrets will engulf them both in a whirlpool of dizzying passion and inescapable danger.
