5. The Alchemist by Paulo Coelho
Madeleine L’Engle isn’t the only one to have a beloved classic reappear on the best-seller list years after it was published. With more than 11,000 reviews and counting – plus high praise from superstars like Neil Patrick Harris and Pharrell Williams – this book’s sales show no sign of slowing down, even on the 25th anniversary of its publication in English. Pretty good for a book Coelho reportedly wrote in two weeks, eh?
