Query: Excellent companion to the Novel.

The Cliff Notes guide to the Scarlet Letter served as a useful companion to the story. Rather than lug around a dictionary to look up complicated words, the Cliff Notes made it easy for the reader to look up the challenging vocabulary in the story. In addition, obscure historical references are explained in the context to the story. The chapter summaries were also useful, particularly in deciphering the middle chapters (9-11), which focus on the psychological battle between the two male main characters of the novel. The Scarlet Letter isn't an easy novel to read, and it really helps to have a guide such as this support your understanding of the novel, particularly a story as influential as this one.However, there is one drawback. The glossary and summary for the twenty-four chapters of the book should also be available for the preliminary story, The Customs House.
