Full summaries of books are available at Sparknotes.com and Cliffsnotes.com. Each book summary listed on the sites also comes with additional information, such as descriptions of main characters, analysis of major themes in the book, and suggestions for essay topics.
The summaries of books provided by Cliffsnotes and Sparknotes are part of comprehensive study guides designed for students reading the books in school. Summaries for most books have two parts. The first is a general summary that covers the main events of the whole book. The second is a more in-depth summary, often divided into chapters or sections, that covers a wider range of events.
