La Brière (translated as Passion and Peat) is a 1923 novel by Alphonse de Chateaubriant that won the Grand prix du roman de l'Académie française for that year. The novel is set in the rustic fenland landscape west of Nantes, known as Brière, in which the traditional occupation of peat-cutting is becoming increasingly unsustainable as the peat runs out. The independence of the local population is threatened by outsiders, who have plans for modernisation.
