Paris, Avignon, and now Manhattan! At the age of 41, Cyril Dewavrin has already taken over or set up three bookstores in France. For his fourth, he decided to cross the Atlantic. Last December, he opened La Joie de Vivre at 145 West 27th Street. For now, the space has been launched as a pop-up with a limited selection of 3,500 books in French and English. Meanwhile, he is finishing work on the “big” bookshop, due to open in mid- March.
