Since the attacks in Paris last Friday, one book has been selling out in bookshops across the city: Ernest Hemingway's A Moveable Feast.

The author's account of living in Paris in his youth is seen as a love letter to the city, its cafes and bars, and the Parisian way of life.

In French its title is translated as "Paris est une fête", or "Paris is a party".

The book has been left at memorial sites, as a symbol of defiance; publishers have ordered it to be reprinted after Paris bookshops ran out of copies.

As young Parisians returned to the cafes and bars of the city a week after the attacks, the BBC's Howard Johnson asked them to share some of Hemingway's reflections on Paris.
