Lucie loves words and people. She writes and publishes novels alongside her work as an instructor, but when a family tragedy shatters her life, she decides to leave everything behind, and moves from Paris to the seaside town of Saint-Malo, Brittany, to recharge her batteries in her grandparents' big old house. She quickly transforms it into a warm and welcoming home for a cast of characters who share their woes and their worries with her. Which turns out to be excellent therapy for Lucie ! 

We meet Léonard, a widowed and grumpy former librarian, Annick, Lucie's protective and admiring mother, Vivianne, a psychologically fragile bookseller, and Camille, a girl in conflict with her family.

The one thing they all have in common is their love of books. Together they develop a thousand projects, starting with a neighbourhood library to share their passion for beautiful words with the inhabitants of Saint-Malo.

Can Lucie silence the demons that consume her soul by helping her strange roommates?
