Dangerous Tides Number 4 in series

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.
