Dead in the Water — Susan Hart

What about spending the weekend on Killian Schiffer's luxury yacht, anchored off Santa Barbara California? He's hired the crew and waiting for his first three passengers. Little does he know that he's in for, literally, the ride of his life when the wealthy couple from South America boards, along with a gorgeous marine biologist from San Diego. He's already bedded his female steward and as she looks on, Schiffer finds an instant sexual attraction to the biologist and wonders if he'll be able to survive his maiden voyage with two women who appear to be after one thing; him. This is a steamy adult romance thriller fresh from the vivid imagination of Susan Hart, who lives in Southern California.
