Returning to Jean Perdu's beautiful barge on the Seine, his Literary Apothercary, where he's spent many years prescribing just the right book to his customers we now come to discover the novel that has been most important to his own life. As his floating bookshop arrives in the soft lights of Provence, Perdu shares the book that has healed him, brought him happiness, anchored him and shown him his way in life. It is comfort and safety in book form, a novel about love, the magic of balmy nights.
