One chance encounter can define a lifetime Erica and Laure meet on the steps of the Sacré-Coeur in Paris, 1978. Erica is a student, relishing her first summer abroad before beginning university at home in England. Laure is studying for her Ph.D. at the Sorbonne, drinking and smoking far too much, and sleeping with a married woman. The moment the two women meet the spark is undeniable. But their encounter turns into far more than a summer of love. It is the beginning of a relationship that will define their lives and every decision they have yet to make. Spanning cities, decades and heartbreaks, fate brings them within touching distance again and again. But will they be brave enough to seize the life they truly want?
