Pickwick is a classic and Dickens first book. It's a book you can read many times without ever tiring of its humor and inventiveness. As the Pickwickians travel around the English countryside by carriage in the year 1827 (before railways ruined everything) you get a vivid picture of English life through characters you will never forget. There is nothing like it in all English literature. You don't want to die without having read Pickwick.
