The owner of the bookshop ‘The Verb To Be', is a red-haired giant imprisoned in an enormous body and his solitude.
One wet afternoon, driving a van load of new and second-hand books, Étienne Vollard knocks down and seriously injures a little girl, Éva. In the hospital, he meets Éva's mother, Thérèse, a struggling single parent who lacks maternal instincts and whose dream is to be faraway, alone.
Both are haunted by guilt: Thérèse because of her lateness in collecting her daughter, and Vollard because he did not
manage to stop his car on time (even if he knows that he could not have avoided Éva: indeed she seemed to throw herself in front of the car). Vollard visits Éva regularly while she is in a coma and reads books to her, while Thérèse
spaces her visits out. When Éva eventually wakes up, she has become mute and is terribly weakened. A few weeks after Éva has been sent to a rehabilitation centre in the Massif de la Chartreuse, Thérèse gets a job faraway and asks Vollard to visit her daughter on her behalf.
Soon, Vollard enjoys their walks in the mountain, where he tells her stories and poems he has memorized and tries to break her out of her mute, impassive shell. However, nothing seems to help "La Petite Chartreuse" - Vollard calls Éva that way in reference to the monastic order of the Chartreux - to enjoy life again. She becomes weaker everyday to such a point that Vollard decides to find Thérèse and to take her back to her daughter before it is too late . . .
