The Kiss - Danielle Steel

Isabelle Forrester is the wife of a prominent Parisian banker who has long since shut her out of his heart. For years, Isabelle has lived a life of isolation, caring for her desperately ill son and her teenage daughter. She allows herself one secret pleasure: a long-distance friendship with a Washington power broker who, like Isabelle, is trapped in an empty marriage. To Bill Robinson, Isabelle is a godsend, a kindred spirit who touches him across the miles. Their relationship is a lifeline that sustains them both through the heartache of marriages they will not betray. Agreeing to meet for a few innocent days in London, Isabelle and Bill find their friendship changing. Then, amid the sudden crash of steel, they are thrust onto a new path fraught with pain but also with possibility.
