Blood Lust

7th in the series. It's the biggest case of their careers and Savannah and Ennis find themselves in a strange competition with their new colleague Cole Jordan. He's a condescending chauvinist bent on driving her crazier than the rash from her radiation treatments. Women are being abducted, tortured, and killed. The killer leaves no evidence. Cole has seen this before and is convinced of one man's guilt. Duke Shelton dominates women for a living. He's handsome, charming and rich and uses all three to his benefit. Initially, Savannah and Ennis are skeptical of Cole's theory but reconsider the idea when Shelton insinuates himself into Savannah's life. When the killer abducts Georgia then Savannah, Ennis is forced to work with Cole - and his belief of Shelton's guilt. Can they find the proof in time to rescue the Georgia and Savannah or will the sisters find a way to save themselves?
