La Peau de Chagrin (English‪)‬

La Peau de chagrin (French pronunciation: ​[la po də ʃaɡʁɛ̃], The Skin of Sorrow or The Wild Ass's Skin) is an 1831 novel by French novelist and playwright Honoré de Balzac (1799–1850). Set in early 19th-century Paris, it tells the story of a young man who finds a magic piece of shagreen that fulfills his every desire. For each wish granted, however, the skin shrinks and consumes a portion of his physical energy. La Peau de chagrin belongs to the Études philosophiques group of Balzac's sequence of novels, La Comédie humaine.
