In a small town in balmy Provence, a dazzling encounter with Love itself changes the life of orphan Marie-Jeanne forever.

As a girl, Marie-Jeanne realizes that she can see the marks Love has left on the people around her - tiny glowing lights on their faces and hands that shimmer more brightly when the one meant for them is near. Before long, Marie-Jeanne is playing matchmaker in her village.

As she grows up, Marie-Jeanne helps her foster father, Francis, set up a mobile library that travels through the many small mountain towns in the region of Nyons. Their library will offer entertainment, guidance, reassurance and comfort - balm for the heartbroken and lonely. Marie-Jeanne soon finds herself bringing soulmates together everywhere they go, with books always playing an essential part in her quest.
