Polo instructor Nicholas Kaharchek senses danger the minute he sees Billie Pearce, a divorced mother of two. She represents everything he's so artfully avoided: a happy home life, parenthood, and stability. To his horror, Nick is fascinated - and irresistibly attracted. When Billie offers to share her home with Nick's crazy cousin Deedee, Nick finds himself visiting - often. But as the sparks begin to fly, Billie and Nick don't realize that danger is lurking where they least expect it, and that a killer is closing in on them.
