Before Isabelle I knew nothing of sex. Before Isabelle I knew nothing of freedom. Before Isabelle I knew nothing of life. Paris in the early Seventies. Sam, an American student, meets a woman in a bookshop. Isabelle is enigmatic, beautiful, older and, unlike Sam, experienced in love's many contradictions. Sam is instantly smitten - but wary of the wedding ring on her finger. What begins as a regular arrangement in Isabelle’s tiny Parisian apartment transforms into a true affair of the heart, and one which lasts for decades to come.
