Showing Dangerous Tides by Christine Feehan

Dr. Libby Drake is sensible and practical. To her more adventurous sisters, she's always been the 'good girl'. Certainly not the kind to attract the attention of a genius like Ty Derrick - until a tragic accident leaves the handsome biochemist at her mercy. Acting on her uncanny ability to heal, she awakens in Ty his own long-suppressed desires. But he's not the only man with designs on Libby Drake. Her miraculous and selfless power has also captured the attention of a dangerously influential admirer. He's pursuing the elementally gifted beauty for his own wicked purpose. And he's willing to go to deadly lengths to make it happen.
