Plot summary.
Although Jessica and Ian Clarke have been married for seven years, they insist that the thrill and excitement have not dimmed. At Jessica's urging, Ian has left his advertising job to become a struggling writer, and she supports him with her successful San Francisco boutique.
Ian's financial dependence on Jessica upsets him more than he admits and, in a moment of bored malaise, Ian's first casual indiscretion will create a nightmare that threatens everything Jessica and Ian have carefully built. What he does changes their lives, and them, perhaps forever, as they struggle to pay the price for his mistake.
